Consider a monopolist with a linear demand curve: q = a − bp, where a;b > 0. It produces at constant marginal cost c and has no fixed cost. Assume that 0 < c < a b.
(a) Find the monopoly price, quantity, and profits. (b) Derive the inverse demand curve P(q). Draw P(q), the MRcurve, and the MC-curve in a diagram. Explain why we need the assumption c < a b. (c) Does it matter that the monopolist sets price instead of quantity? (d) Calculate the deadweight loss of monopoly. (e) A change in b results in two opposing effects on the deadweight loss. Calculate the effect of a change in b on the deadweight loss. (f) Derive the price elasticity of demand η for any price. How does η change with p? (g) Show mathematically as well as graphically that the price elasticity of demand η > 1 at the monopoly price.

At t=0 a grinding wheel has an angular velocity of 27.0 rad/s . It has a constant angular acceleration of 25.0 rad/s2 until a circuit breaker trips at time t = 2.00 s . From then on, it turns through an angle 430 rad as it coasts to a stop at constant angular acceleration.

Through what total angle did the wheel turn between t=0 and the time it stopped?At what time did it stopWhat was its acceleration as it slowed down?

Researchers conducted a study to investigate the effectiveness of two different treatments for depression (Lithium or Imipramine). A sample of individuals diagnosed with bipolar depression were divided into three groups - one group received Lithium, one group received Imipramine, and the last group was given a placebo. After a specified length of time, patients are evaluated for a recurrence of depression. Use StatCrunch to conduct a chi-square test to determine if recurrence is related to the treatment prescribed. In StatCrunch, select Stat > Tables > Contingency > With Data. Select one of the variables of interest for the row variable and the second variable as the column variable. Then click Compute.

  • Select the appropriate hypotheses:
    • HoHo: recurrence of depression is related to the treatment prescribed
      HaHa: recurrence of depression is not related to the treatment prescribed
    • HoHo: recurrence of depression is not related to the treatment prescribed
      HaHa: recurrence of depression is related to the treatment prescribed
  • TS: χ2χ2 =   (round to 4 decimal places)
  • probability =    (round to 4 decimal places)
  • Conclusion: At the 0.10 level, there Select an answer is is not  significant evidence to conclude recurrence of depression Select an answer is not is  related to the treatment prescribed.

Throwback Question: Suppose we know that the risk of liver cancer among alcoholics without cirrhosis of the liver is 29.8%. A researcher conjectures that the risk of cancer among alcoholics with cirrhosis of the liver is higher. Suppose we sample 81 alcoholics with cirrhosis of the liver and determine 29 have liver cancer. Use this information to answer the following:

  1. For each person in the sample, what variable is recorded?
    • number of years diagnosed with cirrhosis
    • level of alcoholism
    • percentage of individuals with liver cancer
    • if the individual has liver cancer
  2. Completely describe the sampling distribution for the sample proportion of alcoholics with cirrhosis who have liver cancer when samples of size 81 are selected (assuming there is no difference in occurrence between those with and without cirrhosis).
    • mean: μˆpμp^  =
    • standard deviation: σˆpσp^ =  (round to 4 decimal places)
    • shape: the distribution of the sample proportion is Select an answer not normally distributed normally distributed

Due to erratic sales of its sole product—a high-capacity battery for laptop computers—PEM, Inc., has been experiencing financial difficulty for some time. The company’s contribution format income statement for the most recent month is given below:

  

Sales (12,700 units × $20 per unit) $ 254,000
Variable expenses 152,400
Contribution margin 101,600
Fixed expenses 113,600
Net operating loss $ (12,000 )

Required:

1. Compute the company’s CM ratio and its break-even point in unit sales and dollar sales.

2. The president believes that a $6,200 increase in the monthly advertising budget, combined with an intensified effort by the sales staff, will result in an $81,000 increase in monthly sales. If the president is right, what will be the increase (decrease) in the company’s monthly net operating income?

3. Refer to the original data. The sales manager is convinced that a 10% reduction in the selling price, combined with an increase of $33,000 in the monthly advertising budget, will double unit sales. If the sales manager is right, what will be the revised net operating income (loss)?

4. Refer to the original data. The Marketing Department thinks that a fancy new package for the laptop computer battery would grow sales. The new package would increase packaging costs by 0.50 cents per unit. Assuming no other changes, how many units would have to be sold each month to attain a target profit of $4,300?

5. Refer to the original data. By automating, the company could reduce variable expenses by $3 per unit. However, fixed expenses would increase by $58,000 each month.

a. Compute the new CM ratio and the new break-even point in unit sales and dollar sales.

b. Assume that the company expects to sell 20,200 units next month. Prepare two contribution format income statements, one assuming that operations are not automated and one assuming that they are. (Show data on a per unit and percentage basis, as well as in total, for each alternative.)

c. Would you recommend that the company automate its operations (Assuming that the company expects to sell 20,200)?
