Given the following historical demand and forecast, calculate the Mean Absolute Percentage Error: Week 1 Demand: 50 Forecast: 49 Week 2 Demand: 54 Forecast: 50 Week 3 Demand: 58 Forecast: 63
FE = D-F n FE RSFE RSFE = 27=1 FE; MFE = n n (FE;) 21-1|FEil MSE = MAD = n n FE; 2i=1 =FE TS = RSFE MAPE n MAD MAD about 6.0%
A. about 2.0%
B. about 18.0%
C. about 4.3%
D. about 1.00%
Answer:
A. about 2.0%
Explanation:
The forecasted error for week 1 is 1%. The demand for week 1 is 50 while estimated demand or forecast was 49. The difference between the two values is 1. The forecasted demand for week 2 is 50 while actual demand for week 2 is 54. The difference between the forecast and actual value is 4. The difference in week 3 is 5. Mean absolute deviation is 6% which means there can be 6% standard deviation from the forecasted values.
The error in Mean Absolute Percentage would be as follows:
A). about 2.0%
What is the Mean Absolute Percentage?
Given that,
Week 1
The error in the forecast = 1%
Demand = 50
Forecasted demand = 49
The difference in the estimated demand and actual demand = 50 -49 = 1
Week 3
The error in the forecast = 1%
Demand = 58
Forecasted demand = 63
The difference in the estimated demand and actual demand = 63 - 58 = 5
Also,
Mean deviation [tex]= 6%[/tex]%
This implies that the standard deviation in the three values is of [tex]6[/tex]%.
∵ 2% is the error
Thus, option A is the correct answer.

A. people in the northeast did not have enough oil to heat their homes, but people elsewhere in the U.S. had enough oil to heat their swimming pools.
B. oil was diverted away from low-value uses (like heating swimming pools) to high-value uses (like heating homes in the northeast).
C. there was not enough oil for heating homes in the northeast or for heating swimming pools elsewhere in the U.S.
D. there was enough oil for heating homes in the northeast and for heating swimming pools elsewhere in the U.S.
Answer: A. people in the northeast did not have enough oil to heat their homes, but people elsewhere in the U.S. had enough oil to heat their swimming pools.
Explanation:
1973 saw the beginning of the energy crises after the Arab world placed an oil embargo on the U.S. As a result, gasoline and oil products became very expensive in the U.S. and had to be appropriately used.
The North-East did not suffer as much during this time New York receiving some of the lowest amounts of snow in modern history so less oil went to the north east for heating as it was ruled not to be cold enough.
Standahl Air uses two measures of activity, flights and passengers, in the cost formulas in its budgets and performance reports. The cost formula for plane operating costs is $40,990 per month plus $2,789 per flight plus $18 per passenger. The company expected its activity in August to be 96 flights and 308 passengers, but the actual activity was 99 flights and 311 passengers. The actual cost for plane operating costs in August was $262,690. The plane operating costs in the planning budget for August would be closest to:
Answer:
$314,278
Explanation:
Cost in flexible budget = $40,990 + ($2,789*96) + ($18*308)
Cost in flexible budget = $40,990 + $267,744 + $5,544
Cost in flexible budget = $314,278
The operating costs in the planning budget for August would be
A large country can gain from imposing a tariff on the import of a good if: Group of answer choices the part of the tariff paid by the foreign exporters is greater than the losses arising from the production and consumption effects of the tariff in the domestic market the tariff is high enough that the country becomes an exporter of the product. the tariff drives the quantity imported to zero. the tariff revenue collected by the domestic government is less than the losses caused by the production and consumption effects of the tariff.
Answer:
part of the tariff paid by the foreign exporters is greater than the losses arising from the production and consumption effects of the tariff in the domestic market
Explanation:
Tariff is a form of tax levied on imported goods. Tariffs increases the price of import. This would discourage foreign exporters because there would be less demand for their good.
Tariffs would reduce the consumption of foreign goods and this would lead to negative welfare effect on consumers. This negative welfare effect can be mitigated if the tariff paid is greater than the welfare losses

The main reason the usefulness of Pareto optimal policies is limited as a policy guide is that: Question 2 options: it is too subjective. it is only objective, and good policy also requires a subjective element. real-world changes in which no one is harmed are rare or nonexistent. real-world changes in which more people are helped than are harmed are rare.
Answer:
real-world changes in which no one is harmed are rare or nonexistent.
Explanation:
Pareto optimality, also known as Pareto efficiency was named after Vilfredo Pareto and it refers to an economic system in which no additional changes can make a person better off without making at least one person worse off.
This ultimately implies that, when there's a maximum level of efficiency in the allocation of goods and resources in an economy and no further changes can be made without making at least one person worse off. Thus, it can only exist in theory but not in reality.
The main reason the usefulness of Pareto optimal policies is limited as a policy guide is that real-world changes in which no one is harmed are rare or nonexistent because the goods and resources cannot be reallocated.
Louisiana Timber Company currently has 5 million shares of stock outstanding and will report earnings of $6.32 million in the current year. The company is considering the issuance of 1 million additional shares that will net $35 per share to the corporation. a. What is the immediate dilution potential for this new stock issue?
Answer:
0.214 per share
Explanation:
Calculation to determine the immediate dilution potential for this new stock issue
First step is to calculate the EPS before issuance
EPS before issuance = 6.32 / 5
EPS before issuance= 1.264
Second step is to calculate the EPS after new share issue
EPS after new share issue = 6.32 / (5+1)
EPS after new share issue=6.32/6
EPS after new share issue= 1.05
Now let calculate the Dilution potential
Dilution potential = 1.264 - 1.05
Dilution potential = 0.214 per share
Therefore the immediate dilution potential for this new stock issue is 0.214 per share

At December 31, 2020, Concord Corporation had a projected benefit obligation of $551,500, plan assets of $313,400, and prior service cost of $134,800 in accumulated other comprehensive income. Determine the pension asset/liability at December 31, 2020. (Enter liability using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).) Pension asset/liability at December 31, 2020
Answer:
$238,100
Explanation:
Calculation to Determine the pension asset/liability at December 31, 2020
Using this formula
Pension asset/liability at December 31, 2020= Projected benefit obligation -Plan assets
Let plug in the formula
Pension asset/liability at December 31, 2020=$551,500 - $313,400
Pension asset/liability at December 31, 2020= $238,100
Therefore Pension asset/liability at December 31, 2020 is $238,100
When the number of units produced equals the number of units sold, ______. Multiple select question. absorption costing net income is greater than variable costing net income absorption costing total expense is greater than variable costing total expense absorption costing net income is equal to variable costing net income all fixed overhead incurred flows to the income statement under both costing methods absorption costing total expense is less than variable costing total expense absorption costing net income is less than variable costing net income
Answer:
absorption costing net income is equal to variable costing net income.
Explanation:
A financial statement is a written report that quantitatively describes a firm's financial health. Under the financial statements is a cash-flow statement, which is used to record the cash inflow and cash equivalents leaving a business firm.
Cash flow statement, also known as the statement of cash flows, contains financial information about operating, financial and investing activities.
Additionally, negotiated transfer prices can be defined as the final price reached between the buyer (consumer) of finished goods and services and the trader (seller) of such goods and services.
When the number of units produced equals the number of units sold, absorption costing net income is equal to variable costing net income as all the fixed overhead are entered into the income statement and thus, there wouldn't be any change in inventory.
You have just purchased a municipal bond with a $10,000 par value for $9,500. You purchased it immediately after the previous owner received a semi-annual interest payment. The bond rate is 6.6% per year payable semi-annually. You plan to hold the bond for 4 years, selling the bond immediately after you receive the interest payment. If your desired nominal yield is 3% per year compounded semi-annually, what will be your minimum selling price for the bond?
Answer:
Minimum selling price for the bond = $11350.38
Explanation:
Given - You have just purchased a municipal bond with a $10,000 par
value for $9,500. You purchased it immediately after the previous
owner received a semi-annual interest payment. The bond rate is
6.6% per year payable semi-annually. You plan to hold the bond for
4 years, selling the bond immediately after you receive the interest
payment. If your desired nominal yield is 3% per year compounded
semi-annually.
To find - What will be your minimum selling price for the bond?
Proof -
Formula for Bond value is -
Bond value = [tex]\frac{Coupon Amount}{( 1+ Interest rate)^{1} } + \frac{Coupon Amount}{( 1+ Interest rate)^{2} } + \frac{Coupon Amount}{( 1+ Interest rate)^{3} } + .....\frac{Coupon Amount}{( 1+ Interest rate)^{n} }[/tex]
As given,
Coupon Rate = 6.6%
⇒Coupon Rate for semi-annual = 3.3%
and hereby time period becomes double i.e 8 years.
Now,
Interest rate = 3%
For semi-annual , interest = 1.5%
Now,
Coupon amount = 10,000×3.3% = 330
Now,
Bond value = 330 ×PVIF(1.5% , 8) + 10,000×IVAF(1.5%, 8)
= 330×7.486 + 10,000×0.888
= 11350.38
∴ we get
Minimum selling price for the bond = $11350.38
Suppose the price of gasoline increases and that sport utility vehicles get poor gas mileage compared to other available cars. One would expect: Select one: a. the demand for gasoline to decrease. b. the demand for sport utility vehicles to decrease. c. the demand for sport utility vehicles to increase. d. the quantity of sport utility vehicles demanded to decrease.
Answer:
b
Explanation:
If the sport utility vehicle has a bad mileage, it means that it burns fuel quickly, so you would have to buy gasoline more frequently.
sport utility vehicle is a complement for gasoline
Complementary goods are goods that are consumed together
If the price of gasoline increases, it would become more expensive to maintain sport utility vehicle. As a result, the demand for sport utility vehicle would decrease. this would shift the demand curve for sport utility vehicle inward.
A increase in the price of gasoline would result in a decrease in the quantity demanded of gasoline and not a reduction in demand.

a. What is Boone’s unemployment rate?
percent
b. Suppose there are 1,000 people who are unemployed as a result of frictional unemployment and 2,000 people who are unemployed as a result of cyclical unemployment. How many people are unemployed as a result of structural unemployment?
Answer:
A. 5.8%
B. 1,000
Explanation:
Calculation for Boone’s unemployment rate
Unemployment rate=[(70,000-1,000)-65,000]/(70,000-1,000)*100
Unemployment rate=(69,000-65,000)/69,000*100
Unemployment rate=4,000/69,000*100
Unemployment rate=5.8%
Therefore Boone’s unemployment rate will be 5.8%
B. Calculation for How many people are unemployed as a result of structural unemployment
Unemployed people=[(70,000-1,000)-65,000]-1,000-2,000
Unemployed people= 4,000 - 1,000 - 2,000
Unemployed people=1,000
Therefore the numbers of people that are are unemployed as a result of structural unemployment will be 1,000
Porter Plumbing's stock had a required return of 10.50% last year, when the risk-free rate was 5.50% and the market risk premium was 4.75%. Then an increase in investor risk aversion caused the market risk premium to rise by 2%. The risk-free rate and the firm's beta remain unchanged. What is the company's new required rate of return? (Hint: First calculate the beta, then find the required return.) Select the correct answer. a. 12.61% b. 11.71% c. 12.01% d. 12.31% e. 12.91%
Answer:
a. 12.61%
Explanation:
E(r)= Rf + B (Rm- Rf)
10.50% = 5.50% + B (4.75%)
10.50% - 5.50% = B * (4.75%)
5% / 4.75% = B
B = 1.0526
New required rate of return = 5.50% + 1.0526*(4.75%+2%)
New required rate of return = 5.50% + 1.0526*(0.0675)
New required rate of return = 5.50% + 7.11%
New required rate of return = 12.61%
An appliance store finding that the contribution margins on appliances are not adequate to achieve performance targets might introduce an extended warranty plan to provide an additional source of contribution margin. A company selling generators may institute an every-six-month service plan that promises both preferential service in a power outage to the customer and considerable contribution margin to the seller to augment the margin associated with the sale of the generator. And, of course, lemonade stand operators might decide to sell pretzels in addition to lemonade. Assume the following base case (per questions A1 and A2): revenue is $100 per unit, variable costs are $20 per unit, and total fixed costs are $40,000. A complementary product/service is being introduced. The product being introduced will use existing resources; however, some additional new costs will be incurred. This product/service will generate additional revenue of $60 per unit, additional variable costs of $16 per unit, and additional fixed costs of $16,240. For every 10,000 original units, the enterprise expects to sell 2,000 complementary units. How many complementary units does the company need to sell to break even
Answer:
Break-even point in units= 369 units
Explanation:
Giving the following information:
Selling price per unit= $60
Unitary varaible cost= $16
Fixed costs= $16,240
To calculate the break-even point in units for the complementary product, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 16,240 / (60 - 16)
Break-even point in units= 369 units

When an import tariff is imposed on an intermediate good, producers of this immediate good in the nation will ____________ while the producers that use the intermediate good as an input will ________. Get better off, get better off Get better off, get worse off Get worse off, get better off Get worse off, get worse off
Answer:
get better off
get worse off
Explanation:
Import are goods or services produced in other countries that are brought into a country.
Import tariff is a form of tax imposed on imported goods. import tariff increases the price of import. the purpose of import is to discourage import
Intermediate good are goods used in the production of finished. An example of an intermediate good is raw materials
When an import tariff is imposed on an intermediate good, producers that use the intermediate goods would be worse off because the price of intermediate goods needed for production would increase as a result of the tariff. This would increase their cost of production and reduce their profit margins
While the producers of the intermediate good in the country would be better off because they would face less foreign competition. Also, they would benefit from the increased price of the intermediate good. This would increase their profit margins.
On January 1, 2018, Como Company purchased 45% of the outstanding common shares of the Lite Company for $200,000. The net assets of Lite Company totaled $400,000. The inventory had a book value of $100,000 and a fair value of $120,000. Excess cost attributable to inventory is written off in 2018. During 2018, Lite Company earned $200,000 and declared a dividend of $40,000 for the year.
The fair value of the Lite stock investment at the end of 2018 was $210,000. Which of the following amounts are correct assuming that Como elected to use the fair value option to account for the Lite investment?
a. $28,000 $210,000
b. $81,000 $263,000
c. $91,000 $273,000
d. $18,000 $210,000
Answer: a. $28,000 $210,000
Explanation:
First column is income and second is Carrying value.
Carrying value is the fair value at year end = $210,000
Income = Dividend received + fair value adjustment
Fair value adjustment = Fair value - cost of shares
= 210,000 - 200,000
= $10,000
Dividend = 45% * 40,000
= $18,000
Income = 18,000 + 10,000
= $28,000
Data related to the expected sales of laptops and tablets for Tech Products Inc. for the current year, which is typical of recent years, are as follows: Products Unit Selling Price Unit Variable Cost Sales Mix Laptops $1,000 $500 40% Tablets 600 300 60% The estimated fixed costs for the current year are $3,192,000. Required: 1. Determine the estimated units of sales of the overall (total) product, E, necessary to reach the break-even point for the current year.
Answer:
Break-even point (units)= 8,400
Explanation:
Giving the following information:
Laptops $1,000 $500 40%
Tablets 600 300 60%
Fixed costs= $3,192,000
To calculate the break-even point for the whole company, we need to use the following formula:
Break-even point (units)= Total fixed costs / Weighted average contribution margin
Weighted average contribution margin= (weighted average selling price - weighted average unitary variable cost)
Weighted average contribution margin= (0.4*1.000 + 0.6*600) - (0.4*500 + 0.6*300)
Weighted average contribution margin= $380
Break-even point (units)= 3,192,000 / 380
Break-even point (units)= 8,400

University Printing Services offer a program of reproducing class notes for participating professors teaching large classes with an enrollment uniformly distributed between 200 and 300 students. Professor Pulat has subscribed to this program. A copy of her notes costs $8 to produce and it sells for $12. The students purchase their books at the start of the semester. Any unsold notes are shredded for recycling as she makes changes to her notes every semester. In the meantime, when all copies are sold, no additional copies are printed. If the University Printing Services wants to maximize its revenues, how many copies should it print
Answer:
233 copies
Explanation:
Cost of shortage (Cs)= Revenue per unit - Cost per unit
Cost of shortage (Cs) = $12 - $8
Cost of shortage (Cs) = $4
Cost of excess (Ce) = Original cost per unit - Salvage value per unit
Cost of excess (Ce) = $8 - $0
Cost of excess (Ce) = $8
Service Level (SL) = Cs/(Cs+Ce)
Service Level (SL) = $4 / ($4+$8)
Service Level (SL) = $4/$12
Service Level (SL) = 0.33
Optimum Level = Minimum student + SL*(Maximum student - Minimum student)
Optimum Level = 200 + 0.33*(300 - 200)
Optimum Level = 200 + 33
Optimum Level = 233 copies
