To test an herbal treatment for acid reflux disease, 100 volunteers who suffered from mild indigestion were randomly divided into two groups. Each person was given a month's supply of tea bags. For one group, the tea contained the herb mixed with green tea, whereas for the other group, the bags contained only the green tea. Participants were not told which type of tea they had, and were asked to drink one cup of tea per day for a month. At the end of the month, a researcher evaluated them to determine if their symptoms had improved. The researcher did not know which of the subjects had the tea with the herbal ingredient added. Which is true regarding this study? The "only green tea" group serves as the control group. This study is an observational study. This study is double-blind. Only (A) and (C) are true. All of the above are true.

Answers

Answer 1

The correct answer is Only (A) and (C) are true

Explanation:

In a study or research, the control group is the one that does not receive a treatment. This means, in this case, the control group includes those who only drink the green tea without the herbs because they serve as a standard to measure the effects of the herbs. This makes statement A (The "only green tea" group serves as the control group) true; also, the group receiving the herbs is the experimental group.

On the other hand, a double-blind study is one in which the researchers and the participants ignore who is receiving the treatment, which guarantees there is objectivity. This occurs in the study presented because neither the researcher nor the subjects known who received the herbal mix. Thus, statement C (This study is double-blind) is true.

Finally, a study is classified as observational if there is not intervention but the researchers just observe participants to study a phenomenon. This does not occur in the study presented because there is an intervention through the herbal treatment, and therefore the study is not observational.

How do economists use economic models

Answers

Answer:

Economists use economic models to study particular aspects of economic reality. To do so, they develop a simplified model of reality in which only a few variables are included, and everything else is held constant or ignored.

Explanation:

For example, the most famous economic model is the model of supply and demand, which is used to analyze how consumers and producers interact in the market for a good or service, and how this interaction determines the price.

As we can see, in this economic model of supply and demand, many other things like social class or history are left aside, and only a few variables are included.

Phoenix Guitars is interested in pursuing backward integration to take greater ownership of the extraction of raw materials and production of components used in its signature line of guitars. Although this approach would lower the overall cost of producing a guitar, the costs associated with producing electronic pickups for sound amplification are far greater than those associated with sourcing pickups from a reliable supplier. Which of the following approaches is likely to produce superior results?
A) Invest in vertical integration despite the cost of producing pickups.
B) Abandon the idea of vertical integration entirely.
C) Pursue taper integration.
D) Introduce a budget line of guitars to diversify the firm's offeri

Answers

Answer:

Option A

Explanation:

In simple words, Regardless of the expense of making guitars, the technique reduces the total cost of manufacturing a instrument. Phoenix would be in the production business of instruments, not pickups.

The target of this technique is therefore the entire guitar, not really the pickups. The smaller the process of manufacturing their instruments, the better manoeuvrability they have on the market. When they have reduced costs, they may change rates downwards in order to capture further market penetration.

Assume that we are in the MM world. Health and Wealth Company is financed entirely by common stock that is priced to offer a 12 percent expected return. If the company repurchases 20 percent of the common stock and substitutes an equal value of debt yielding 8 percent, what is the expected return on the common stock after refinancing

Answers

Answer:

13%

Explanation:

the new cost of equity = old cost of equity + [(debt / equity) x (old cost of equity - cost of debt)]

the new cost of equity = 12%+ [(20 / 80) x (12% - 8%)] = 12% + 1% = 13%

Since we are in the MM world, taxes do not exist, therefore they are not included in the equation.

(hint: calculate finance charge before adding $45.00 to the balance.) $9,428.47 $9,222.08 $9,267.08 $9,429.25

Answers

Answer: $9428.47

Explanation:

Given the following :

Periodic rate = 1.75% = 0.0175

Previous balance = $9472.08

Payments and credit = $250

New purchase = $45

Unpaid balance = previous balance - payments and credit

Unpaid balance = $9,472.08 - $250 = $9222.08

Finance charge = unpaid balance × periodic rate

Finance charge= $9222.08 × 0.0175 = $161.3864

New balance = (unpaid balance + finance charge + new purchase)

New balance = $(9222.08 + 161.3864 + 45)

New balance = $9428.4664

New balance = $9,428.47

Douglas Industries produced 5,500 units of product that required 2.5 standard hours per unit. The standard fixed overhead cost per unit is $2.20 per hour at 13,500 hours, which is 100% of normal capacity. Determine the fixed factory overhead volume variance.

Answers

Answer:

$550 favorable

Explanation:

Douglas industries was involved in the manufacturing of 5,500 units of a product which required 2.5 standard hours per unit.

The standard fixed overhead cost per unit is $2.20 for each hour at 13,500 hours

Therefore, the fixed factory overhead volume variance can be calculated as follows

= (13,500-(5,500×2.5hours)×$2.20

= (13,500-13,750)×$2.20

= -250 × $2.20

= -$550

= $550 favorable

Hence the fixed factory overhead volume variance is $550 favorable

Company FM2 must pay 200,000 in 4 years. In order to fully immunized from changes in interest rate, the company invests in a 3 year zero coupon bond that matures for 90,000 and a 5 year zero coupon bond that matures for X. The actuary for Company FM2 determined that their portfolio fully immunized their ability to meet their obligations at the current interest rate i. Calculate X.

Answers

Answer:

11.10%

Explanation:

The computation of the X is shown below;

The first equation is

$90,000 ÷ ( 1 + interest rate)^3 + X ÷ (1 + interest rate)^5 = $200,000 ÷ (1 + interest rate)^4

$90,000 × (1 + interest rate)^2 + X = $200,000 × (1 + interest rate)..........(I)

As we are assuming company has invested in both the bonds

So,

The second equation is

$90,000 (1 + interest rate)^2 = X ...................................(2)

By considering the both equation

we can derive that

X = $100,000 × (1 + interest rate)

Now the (1 + interest rate) is

= $100,000 ÷ $90,000

= 11.10%

Van and her brother Trung both own homes valued at $175,000. Both pay property taxes at 1.25% and pay annual taxes of $2,187.50. They live in different neighborhoods. Van’s property value is expected to increase by 5% next year.Trung’s property value is expected to increase by 3%. How will these changes affect their property taxes? Check all that apply.

Answers

Answer:

Van's property tax will increase.

Trung's property tax will be less than Van's.

Trung's property tax will increase.

Explanation:

Data provided in the question

Value of the home = $175,000

Property taxes = 1.25%

Annual taxes = $2,187.50

Increased percentage for Van = 5%

Increased percentage for Trung = 3%

based on the above information, the affect is as follows

Van's property tax would rise as he expects his home's value to rise more than Trung's property value. Since the value of Van 's property is rising and rising more than that of Trung, Trung's would be less than that of Van. Because of the rise in value Trung's property tax is rising.

Explanation:

The difference between actual and standard cost caused by the difference between the actual quantity and the standard quantity is called the Quantity variance.

For instance, if Tony needs a standard quantity of 50 pounds of iron to construct a burglary, but only used 51 pounds, then the quantity variance is 1 pound of iron.

JVL Enterprises has set a target profit of $126,000. The company sells a single product for $50 per unit. Variable costs are $15 per unit and fixed costs total $98,000. How many units does JVL have to sell to BREAK-EVEN?

Answers

Answer:

The break even unit is 2800 units.

Explanation:

The target profit of JVL Enterprises = $126000

The selling price of a single unit (SP) = $50 per unit.

Variable cost (VC) = $15

Fixed cost of the production (FC) = $98000

Now find the break-even unit by dividing the fixed cost with the difference of selling price and variable cost.

The break even unit = FC / (SP-VC)

= 98000 / (50 – 15)

= 2800 units

All of the following are assumptions of cost-volume-profit analysis except a.the sales mix is constant. b.costs can be divided into fixed and variable components. c.there is no change in inventory quantities during the period. d.within the relevant range of operating activity, the efficiency of operations can change.

Answers

Answer:

d. within the relevant range of operating activity, the efficiency of operations can change.

Explanation:

Cost-volume-profit analysis is also known as the break even analysis, it is an important tool in predicting the volume of activity, the costs to be incurred, the sales to be made, and the profit to be earned is. It is used to determine how changes in differing levels of activities such as costs and volume affect a company's operating income and net income.

Generally, to use the cost-volume-profit analysis, financial experts usually make some assumptions and these are;

1. Sales price per unit product is kept constant.

2. Variable costs per unit product are kept constant and the total fixed costs of production are kept constant i.e costs can be divided into fixed and variable components.

3. All the units produced are sold i.e there is no change in inventory quantities during the period.

5. The costs accrued are as a result of change in business activities.

6. A company selling more than a product should simply sell in the same mix i.e the sales mix is constant.

Hence, the aforementioned are assumptions of cost-volume-profit analysis except that, within the relevant range of operating activity, the efficiency of operations can change.

All of the following are assumptions of cost-volume-profit analysis except within the relevant range of operating activity, the efficiency of operations can change. Thus, option D is the correct option.

The break-even analysis, also known as cost-volume-profit analysis, is a crucial technique for forecasting the amount of activity, expenditures to be incurred, sales to be produced, and profits to be realized. It is employed to assess how variations in various activity levels, such as expenses and volume, impact an organization's operating income and net income.

Financial professionals typically utilize the cost-volume-profit analysis and base their decisions on the following assumptions:

The unit sales price of the product is constant.The overall fixed costs of production are maintained at a consistent level, allowing for the division of costs into fixed and variable components.
