1.A manufacturer of mountaineering equipment produces traditional​ three-strand climbing rope on two separate production​ lines, line 1 and line 2. The manufacturer regularly tests the tensile strength of its ropes by randomly selecting ropes from production and subjecting them to various tests. The results from the most recent random sample of ropes are shown below.

Assuming the population of tensile strengths for each line is approximately normally distributed with equal​ variances, can the manufacturer conclude there is a difference between the mean tensile strengths of ropes produced on the two​ lines? Conduct the appropriate hypothesis test at the 0.01 level of significance.

. The government imposes a price floor of $8 per unit.

1. Draw a clearly marked graph to illustrate the demand, supply, competitive equilibrium

point (without government intervention), and the price floor.

2. Compute the equilibrium price and quantity after the price floor and interpret the results.

3. Explain who benefits and who loses from this measure and by how much. What can you

Savemore store is a retail store that sells many different types of items and many different brands. The store has plain clothes security workers who walk around the store and watch customers to monitor and limit theft of merchandise.

Charley Customer enters Savemore and is seen walking down the clothing aisles looking at different clothing for sale at the store. Charley Customer has a shopping cart with him and makes his way to the registers to pay for the items in the shopping cart.

Sue, an undercover security worker, is doing her regular rounds and notices a tag and hanger clip torn off a belt and thrown in the middle of some folded shirts on a lower shelf. She did not see who removed the tag and hanger, but confirms the belt is missing. She radios to the other security workers what she discovered.

Security worker Mike recalls that he observed Charley Customer in the clothing aisles and jumps into action by running out to the parking lot and tackling Charley Customer and detaining him on suspicion that he took the belt. It is later realized that Charley Customer did NOT take the belt as the store surveillance video confirmed that the belt was taken earlier that day by another customer who already left the store.

Charley Customer is detained for approximately 30 minutes while the security workers investigate the situation. When they apologize to Charley Customer, he is so frustrated, he grabs a stack of papers off the desk in the security office and throws them at Sue! Sue was terrified as she saw Charley Customer get upset and start to throw the papers at her; thankfully she was able to move out of the way and not get hit.

Explain what claim, or claims, Charley Customer may potentially bring against Savemore and the security workers. Be specific in the types of claims and explain why they may apply.

Explain what claim, or claims, Sue may be able to bring against Charley Customer and explain why in detail.

What is the sequence of events in the Relentless Profit Squeeze and compare to the sequence of events facing a monopoly

please answer soon anyone

Phillip was waiting for a bus at a bus stop. Across the street and down the block, a mechanic negligently overinflated a tire he was intending to put onto Marsha’s pickup truck. The exploding tire injured Marsha and frightened a neighborhood dog, which ran down the street and knocked Phillip down, injuring his knee. Phillip sued the mechanic. In applying the Palsgraf v. Long Island Railroad Co. decision to this case, explain in detail why or why not the mechanic would be liable and provide a thorough analysis. Make sure to apply the facts of this situation to the Negligence Analysis as well with particular focus on the Palsgraf application.

Consider the following regression equation for the United States (standard errors in parentheses):

            where: P_t      = per capita pounds of pork consumed in time period t

                        PRP_t = the price of pork in time period t

                       PRB_t = the price of beef in time period t

                       YD_t   = per capita disposable income in time period t

(a) Hypothesize signs and specify the appropriate null and alternative hypotheses for the coefficients of each of these variables.

(b) State your decision rules and then test your hypotheses on the above results using the t-test at a 5% level of significance.

(c) If you could add one variable to the regression, what variable would you add? Why?

1.Explain why economists advocate that regulators use marginal-cost and not average-cost pricing. Also explain why regulators favor average cost pricing.

2. Provide the formula for how a Public Utility Commission determines the rate-of-return. Then relate it to the Averch-Johnson Effect.

3. Draw a graph that shows the social welfare loss from a flat rate as compared to using a peak and off-peak rate. Explain.

4. Why is it a challenge to utilities to promote energy efficiency? How might decoupling reduce the challenge?

1) Explain the similarities and differences between monopolistically competitive markets, monopolies, and perfectly competitive markets.

2) Does the presence of asymmetric information in a market justify governmental intervention? Justify your answer using economic principles.

Analyze the following statements regarding the US external position:

a. The deterioration of the Net Foreigner Asset position means that foreign holdings of US issued assets have increased while domestic holdings of foreign issued assets have not increased.

b. The increase in the fiscal deficit in the last decades contributed to the current account deficits.

c. Investments in the US have been larger than domestic Savings which is equivalent to incurring a fiscal deficit.

Explain which statement is correct (and why) and why the others are incorrect.

Suppose that the supply of bourbon (unit = 1 bottle) is given by P = 3Q. The demand for

bourbon is given by P = 100 – Q. Suppose the government introduces a tax on bourbon of $12 per

bottle, to be paid to the government by consumers.

a. What is the deadweight loss associated with this $12 tax on each bottle of bourbon?

b. How much of the deadweight loss is borne by consumers? How much is borne by suppliers?
