A​ monopolist's maximized rate of economic profits is ​$1500 per week. Its weekly output is 500 ​units, and at this output​ rate

, the​ firm's marginal cost is ​$32 per unit. The price at which it sells each unit is ​$42 per unit. At these profit and output rates, what are the firm's average total cost and marginal revenue?

Answer:

Average total cost = $39

Marginal revenue = $32 per unit

Explanation:

The computation of average total cost and marginal revenue is shown below:-

Average total cost = Selling price - (Economic profit ÷ Weekly output)

                              = $42 - ($1,500 ÷ 500)

                              = $42 - 3

                              = $39

Marginal revenue = Marginal cost

So,

Marginal revenue = $32 per unit

Therefore for computing the average total cost and marginal revenue we simply applied the above formula.

c. An index of 10,000 corresponds to a monopoly firm with 100% market share

Explanation:

Here are the options to the last question

Why is the largest possible value of the Herfindahl index 10,000 ?

a. An index of 10,000 corresponds to 100 firms with a 1% market share each

b. An industry with an index higher than 10,000 is automatically regulated by the Justice Department

c. An index of 10,000 corresponds to a monopoly firm with 100% market share

HHI index = 60²  + 20² + 20² = 4400

If one of the firms leaves the industry, the market share would be distributed between the two firms and this would cause the HHI index to increase as firm's concentration would increase

If only one firm operates in the industry, its market share would be 100% and its HHI index would be 100² = 10,000. For an industry to exist there has to be at least one firm operating in the industry,

The Centers for Disease Control and Prevention (CDC) defines a healthy sleep duration
laiz [17]

a. The point estimate of the married people that sleep well is = 0.6299. The confidence interval for the mean hours of sleep for those that have never been married but report good sleep is 0.6186, 0.6412

b. The point estimate of the number of hours for people that have never been married = 7.2257

95% confidence interval for the mean number of  hours of sleep for those who have never been married = 7.2065, 7.2447

c. the estimated number of sleep for those that have never been married = 7.729 hours

a. The point estimate

P=\frac{Xp}{n}

Xp = successes\\n = sample size\\

Those who have never been married n = 7044

Xp = those who sleep for 7 hours at least

To get Xp, the <u>excel function </u>

Countif(range, criteria)

Countif(A:A, >=7)

This gives Xp = 4437

Point estimate =

\frac{4477}{7044}

= 0.6299

The point estimate of the married people that sleep well is = 0.6299

At 95% interval of confidence,

α = 1-0.95 = 0.05

α/2 = 0.05/2 = 0.025

Z0.025 = 1.96 ( Use the standard probability normal table)

Margin of Error

=M.E = 1.96\sqrt \frac{0.6299(1-0.6299)}{7044} \\\\= 1.96\sqrt{0.000033} \\\\1.96*0.0057

= 0.0113

The 95% confidence interval

= 0.6299 - 0.0113 , 0.6299 + 0.0113

= 0.6186, 0.6412

The confidence interval for the mean hours of sleep for those that have never been married is 0.6186, 0.6412

b. Sample mean

x = ∑x/n

x = number of sleep of the never been married

Mean is calculated using excel function

Average(range)

Average(a:a)

This gives the sample mean = 7.2257

The point estimate of the number of hours for people that have never been married = 7.2257

<u>Standard deviation</u> using excel =

Stdev(A:A) = 0.8211

Margin of error =1.96*\frac{0.8211}{\sqrt{7044} }

= 0.0192

The<u> confidence interval</u> =

= 7.2257-0.0192, 7.2257+0.0192

= 7.2065, 7.2447

95% confidence interval for the mean number of  hours of sleep for those who have never been married = 7.2065, 7.2447

c. From the available data, the mean number of sleep per day that is gotten from the 4437 people that are unmarried and sleep healthily for at least 7 hours = 34295.1

Mean = 34295.1/4437

= 7.729

the estimated number of sleep for those that have never been married = 7.729 hours
