Suppose a company's revenue function is given by R(q)=−q^3+360q^2 and its cost function is given by C(q)=300+19q where q is hundreds of units sold/produced, while R(q) and C(q) are in total dollars of revenue and cost, respectively.

A) Find a simplified expression for the marginal profit function. (Be sure to use the proper variable in your answer.)

MP(q)=

B) How many items (in hundreds) need to be sold to maximize profits? (Round your answer to two decimal places.)

Answer: hundred units must be sold.

Assume a firm is a monopsonist that can hire its first worker for $6 but must increase the wage rate by $3 to attract each successive worker (so that the second worker must be paid $9, the third $12, and so on). The marginal revenue product of labor is given in the table .

a. Draw the firm’s labor supply and marginal resource cost curves.

Are the labor supply and MRC curves the same or different? If they are different, which one is higher?

b. What is the competitive equilibrium wage rate?

What is the equilibrium level of employment?

c. What is the wage rate under monopsonistic conditions?

What is the equilibrium level of employment under monopsonistic conditions?

By how much does the monoposonist reduce wages below the competitive wage?

By how much does the monopsonist reduce employment below the competitive level?

Question 3

Information pertaining to Yekstop Corp.'s sales revenue is presented below:

Management estimates that 3% of credit sales are eventually uncollectible. Of the collectible credit sales, 60% are likely to be collected in the month of sale and the remainder in the month following the month of sale. The company desires to begin each month with an inventory equal to 75% of the sales projected for the month. All purchases of inventory are on open account; 20% will be paid in the month of purchase, and the remainder paid in the month following the month of purchase. Purchase costs are approximately 50% of the selling prices.

Total budgeted inventory purchases in November by Yekstop Corp. are:

Multiple Choice

• $222,375.

• $272,625.

• $402,000.

• $423,375.

• $535,782.

3. What benchmark would you use to calculate materiality? Why? ((a)Net Income, (b) Assets, (c) Revenue, or (d)Equity.) (Pick 1 letter & Explain why)

a. 5 percent to 10 percent of net income before taxes.

b. ½ percent to 1 percent of total assets.

c. ½ percent to 1 percent of total revenues.

d. ½-1 percent of total equity.

4. Would you use a higher percentage or a lower percentage for the benchmark you selected in Q3 above. (EX: 5% of Net Income vs 10% of Net Income)? Explain why?

5. Using the choices from Q3 & Q4 above calculate “overall materiality” for your audit for 2019? (ex: Benchmark %(1%) * Assets ($25m)= $250K (Overall Materiality)).

Why is it important for protocol information to be published? What can you do if the protocol that you are working on does not have any publicly available information? Is there any one tool that is better than the rest? If so, why is it better? If not, how do you choose which tool to use when there are so many options?

Problem 4: House Prices

Use the “Fairfax City Home Sales” dataset for parts of this problem.

a) Use StatCrunch to construct an appropriately titled and labeled relative frequency histogram of Fairfax home closing prices stored in the “Price” variable. Copy your histogram into your document.

b) What is the shape of this distribution? Answer this question in one complete sentence.

c) Assuming the population has a similar shape as the sample with population mean $510,000 and population standard deviation $145,000; calculate the probability that in a random sample of size 10, the mean of the sample will be greater than $600,000. You may assume a random sample was taken and the sample came from a big population. However, be sure to check the central limit theorem condition of a large sample size before completing this problem using one complete sentence. If this condition is not met, you cannot complete the problem.

d) Assuming the population has a similar shape as the sample with population mean $510,000 and population standard deviation $145,000; calculate the probability that in a random sample of size 36, the mean of the sample will be greater than $600,000. You may assume a random sample was taken and the sample came from a big population. However, be sure to check the central limit theorem condition of a large sample size before completing this problem using one complete sentence. If this condition is not met, you cannot complete the problem.
