7. Suppose that next year we again will collect data and will want to estimate the mean height of the entire female/male SCC student body. The minimum sample size we need to take depends on what confidence level and margin of error we specify.

(n≥30, use section 6.1 as a guide for this question, use ? = (s) answer from 2c, remember round answers up!)

a. Determine the minimum sample size needed to be 94% confident that the sample mean we get is within ¼ inch of the true mean.

b. Determine the minimum sample size needed to be 94% confident that the sample mean is within ½ inch of the true mean.

c. Determine the minimum sample size needed to be 90% confident that the sample mean is within ½ inch of the true mean

Minden Company introduced a new product last year for which it is trying to find an optimal selling price. Marketing studies suggest that the company can increase sales by 5,000 units for each $2 reduction in the selling price. The company’s present selling price is $91 per unit, and variable expenses are $61 per unit. Fixed expenses are $832,800 per year. The present annual sales volume (at the $91 selling price) is 25,300 units.

Required:

1. What is the present yearly net operating income or loss?

2. What is the present break-even point in unit sales and in dollar sales?

3. Assuming that the marketing studies are correct, what is the maximum annual profit that the company can earn? At how many units and at what selling price per unit would the company generate this profit?

4. What would be the break-even point in unit sales and in dollar sales using the selling price you determined in (3) above (e.g., the selling price at the level of maximum profits)?

If the money supply is growing at a rate of 3 percent per​ year, real GDP​ (real output) is growing at a rate of 0 percent per​ year, and velocity is growing at 3 percent per year instead of remaining​ constant, what will the inflation rate​ be?

A condensed income statement for the Commercial Division of Maxell Manufacturing Inc. for the year ended December 31, 20Y9, is as follows:

Assume that the Commercial Division received no charges from service departments. The president of Maxell Manufacturing has indicated that the division’s return on a $3,250,000 investment must be increased to at least 20.00% by the end of the next year if operations are to continue. The division manager is considering the following three proposals:

Proposal 1: Transfer equipment with a book value of $317,500 to other divisions at no gain or loss and lease similar equipment. The annual lease payments would exceed the amount of depreciation expense on the old equipment by $106,000. This increase in expense would be included as part of the cost of goods sold. Sales would remain unchanged.

Proposal 2: Purchase new and more efficient machining equipment and thereby reduce the cost of goods sold by $565,000 after considering the effects of depreciation expense on the new equipment. Sales would remain unchanged, and the old equipment, which has no remaining book value, would be scrapped at no gain or loss. The new equipment would increase invested assets by an additional $1,818,000 for the year.

Proposal 3: Reduce invested assets by discontinuing a product line. This action would eliminate sales of $592,000, reduce cost of goods sold by $412,700, and reduce operating expenses by $176,500. Assets of $1,378,000 would be transferred to other divisions at no gain or loss.

Starting Question

Proposal 3

Proposal 2

5. If the Commercial Division were in an industry where the profit margin could not be increased, how much would the investment turnover have to increase to meet the president’s required 20.00% return on investment? Enter your increase in investment turnover answer as a percentage of current investment turnover. If required, round your intermediate and final answers to two decimal places.

A 42 year old woman was introduced to the Emergency Room with complaints of abdominal pain for the past few days. She was also reported her stools have been black and sticky. She suspected to have GI (gastro-intestinal) bleeding. According to her medical history, she was transfused with 2 units washed packed RBCs 6 months ago for the same symptoms. The CBC results were:

WBCs: 5.7 X 103/µl

RBCs: 2.95 X 106/µl

HGB: 6.3g/dL

Hematocrit: 19.8%

According to her anemic condition, she was admitted to the hospital for treatment and given 3 units of packed RBCs (each blood unit should increase hemoglobin level by 1g/dL, but she was given 3 units since she had an active GI bleeding). She is type B positive with a negative antibody screening {1} which means no antibodies were observed in her plasma. The 3 units were cross-matched and transfused without adverse reactions. One day later, she was discharged. Two days after discharge, she returned to the Emergency Room with yellowish eyes and skin (jaundice). The CBC at this time showed HGB = 5.8g/dL and elevated bilirubin level indicated hemolysis of RBCs. She was ordered with 2 units of packed red blood cells. At this time, the antibody screen was now positive {2}. Anti-JKb was found in her plasma and positive DAT was observed.

She was diagnosed with a delayed hemolytic transfusion reaction (DHTR) due to anti-JKb

1.       Discuss this condition DHTR?

2.       Why the first antibody screening {1} was negative? (Knowing that anti-JKb was present in her plasma from exposure of JKb positive blood via previous blood transfusion according to her medical history)? However, it is really negative since no immediate HTR was observed

3.       Why the second antibody screening{2} becomes positive after blood transfusion?

4.       If DAT was performed by gel-method, and positive mixed field result was observed. What does this mean?
