A medical facility does MRIs. Occasionally, the test yield inconclusive results and have to be repeated. Using the following sample data and n = 100, determine the UCL (to three decimals) for a two-sigma control chart.
Sample 1 2 3 4 5 6 7 8 9 10
Number of Retests 4 11 6 10 4 6 1 6 9 11
a) 0.118.
b) 0.068.
c) 0.144.
d) 0.129.

Answer 1

Answer:

a) 0.118.

Explanation:

The computation of the UCL is shown below:

Given that

N = 100

Sample    Sample size      Number of retests       fraction defective

1                      100                     4                                0.04

2                     100                      11                               0.11

3                     100                      6                               0.06

4                     100                      10                              0.1

5                     100                     4                                0.04

6                     100                      6                              0.04

7                     100                      1                                0.01

8                     100                      6                               0.06

9                     100                      9                              0.09

10                   100                      11                               0.11

Total              1,000                   68

Now p is

= 68 ÷ 1000

= 0.068

Now the standard deviation is

= √p(1 - p) ÷ √n

= √0.068 × (1 - 0.068) ÷ √100

= 0.025

Now the UCL is

= p + z × standard deviation

= 0.068 + 2 × 0.025

= 0.118

Siskiyou Corp. has cash of $75,000; short-term notes payable of $100,000; accounts receivables of $275,000; accounts payable of $135,000: inventories of $350,000; and accrued expenses of $75,000. What is the firm's net working capital

Answers

Answer: $390000

Explanation:

First and foremost, we need to calculate the current assy from the given question which would be:

= $75000 + $275000 + $350000

= $700,000

Also, the current liabilities will be:

= $100000 + $135000 + $75000 = $210000

Therefore, the firm's net working capital willbe the difference between the assets and the liabilities calculated above. This will be:

= $700,000 - $210,000

= $390,000

You own a portfolio that has $2,950 invested in Stock A and $3,700 invested in Stock B. If the expected returns on these stocks are 8 percent and 11 percent, respectively, what is the expected return on the portfolio

Answers

Answer:

9.67%

Explanation:

The total value of the portfolio = $ 2,950 + $ 3,700  = $6,650

The proportion of the portfolio invested in stock A = $ 2,950 / $ 6,650 = 44.36% . The proportion of the portfolio invested in stock B = 100 - 44.36%  = 55.64%

The expected return of the portfolio = 0.4436*0.08 + 0.5564*0.11  = 0.035488 + 0.061204 = 0.096692 = 9.67%

Which of the following is true of marginal product? Select one:
a. When marginal product is negative, total product is increasing
b. When marginal product is increasing, total product is decreasing.
c. When marginal product is positive and decreasing. total product is decreasing.
d. When marginal product is positive and decreasing. total product is increasing by increasing amounts.
e. When marginal product is increasing, total product is increasing by increasing amounts.

Answers

Answer: When marginal product is increasing, total product is increasing by increasing amounts.

Explanation:

The marginal product is simply referred to as the additional output that is created due to the fact that an additional input has been placed into that particular organization or company.

The option thst is true of marginal product is option E "When marginal product is increasing, total product is increasing by increasing amounts".

We should also note that when the marginal product is reducing, but is still positive, then the total product will be increasing even though it'll now be at a decreasing rate.

Answers

Answer:

Hi, your question is incomplete, I tried to look for it online but i could not find it.

Here are some explanations on ways to calculate the required amounts.

Part A

Direct Material Cost

This is a component used in manufacturing a product and is found in the manufacturing account.

To calculate the Direct Material costs, we deduct the Ending Material Inventory amount from the Total of Beginning Material Inventory and Material Purchases made during the period

Part B

Indirect Labor Cost

This is also a component found in the manufacturing Account.

Indirect labor costs are calculated by deducting the direct labor costs from the total labor costs incurred during the manufacturing period.

Part C

Total Overheads Costs

This is also a component found in the manufacturing Account.

Overheads are manufacturing expenses that can not be directly traced to the product being produced. Examples are electricity, water and factory rent. So add up these expenses to arrive at the amount overheads.

Part D

Costs of Goods Manufactured

This is an amount reported in the manufacturing account.

To calculate the cost of goods manufactured we add the Opening Work In Process Inventory to the Total Manufacturing Costs incurred during the period then deduct the Ending Work In Process Balance.

Part E

Cost of Goods Sold

This is an amount reported in the Trading account for profit determination.

To calculate the Cost of Goods Sold, we add the Beginning Finished Inventory Balance to the amount of Cost of Goods Manufactured then deduct the Ending Balance in Finished Inventory.

Part F

Gross Profit

This is an amount reported in the Trading account for profit determination.

To calculate the Gross Profit , we deduct the Cost of Goods Sold from the Total Sales made during the Trading period.
