The chief economist for Argus Corporation, a large appliance manufacturer, estimated the firm’s short-run cost function for vacuum cleaners using an average variable cost function of the form AVC = a + bQ + cQ2 where AVC = dollars per vacuum cleaner and Q = number of vacuum cleaners produced each month. Total fixed cost each month is $180,000. The following results were obtained: a) Are the estimates ˆa ,ˆb , and cˆ statistically significant at the 2 percent level of significance? Which is/are significant and which is/are not? b) Do the results indicate that the average variable cost curve is ∪-shaped? How do you know?c) If Argus Corporation produces 8,000 vacuum cleaners per month, what is the estimated average variable cost? Marginal cost? Total variable cost? Total cost? d) Answer part c, assuming that Argus produces 10,000 vacuum cleaners monthly. e) at what level of output will average variable cost be at a minimum? What is the minimum average variable cost?
You give a final attempt to bring the effect of Size back into the equation by forcing the assumption of homoskedasticity onto your estimation. The results are as follows: cost^= = 7,311.17 + 3,985.20 × Reputation – 0.20 × Size (1,985.17) (593.65) (0.07)+ 8,406.79 × Dpriv – 416.38 × Dlibart – 2,376.51 × Dreligion (1,423.59) (1,096.49) (989.23) R 2=0.72, SER = 3,682.02Calculate the t-statistic on the Size coefficient and perform the hypothesis test that its coefficient is zero. Is this test reliable? Explain.
Airphone, Inc., manufactures cellular telephones at a pro-cessing cost of $47 per unit. The company produces an average of 250 phones per week and has a yield of 87%good-quality phones, resulting in 13% defective phones,all of which can be reworked. The cost of reworking adefective telephone is $16.a. Compute the quality-productivity ratio (QPR).b. Compute the QPR if the company increased theproduction rate to 320 phones per week while reducingthe processing cost to $42, reducing the rework cost to$12, and increasing the product yield of good-qualitytelephones to 94%.
A business wants to lower its price level to increase sales of its goods. However, for the price reduction to be beneficial, the increase in sales after the price decrease must be greater than 10%. After the business lowers its prices, it monitors its sales for 60 days and determines that the rate of increase in sales is 13% on average. Should the business maintain the low price level practice? What is the hypothesis and decision for α = 0.05? H0 : P ≤ 0.13 H1 : P > 0.13, Decision: Ho cannot be rejected. H0 : P = 0.10 H1 : P < 0.10, Decision: Ho is rejected. H0 : P = 0.13 H1 : P ≠ 0.13, Decision: Ho is rejected. H0 : P = 0.10 H1 : P ≠ 0.10, Decision: Ho cannot be rejected. H0 : P ≤ 0.10 H1 : P > 0.10, Decision: Ho cannot be rejected.

The U.S. government wants to determine whether immigrants should be tested for a contagious disease, and it is planning to base this decision on financial considerations. Assume that each immigrant who is allowed to enter the United States and has the disease costs the country $100,000. Also, assume that each immigrant who is allowed to enter the United States and does not have the disease will contribute $10,000 to the national economy. Finally, assume that x percent of all potential immigrants have the disease. The U.S. government can choose to admit all immigrants, admit no immigrants, or test immigrants for the disease before determining whether they should be admitted. It costs T dollars to test a person for the disease, and the test result is either positive or negative. A person who does not have the disease always tests negative. However, 10% of all people who do have the disease test negative. The government’s goal is to maximize the expected net financial benefits per…
A shoe wholesaler wants to optimize its shipment of shoes to its client retailers. To minimize their turnover time and avoid building up stocks that add costs, the wholesaler wants to know if weather conditions are important in determining the type of shoe demanded. Specifically, she / he would like to know if high temperatures affect the sale of closed, rubber-heeled walking shoes. He / she has the relevant data showing the temperature recorded at the location of its retail shops, as well as their record of sales of these walking shoes, during each day of the past year. What type of analysis should he / she conduct? What variables should be considered? Explain.
The owner of a moving company typically has his most experienced manager predict the total number of labor hours that will be required to complete an upcoming move. This approach has proved useful in the past, but the owner has the business objective of developing a more accurate method of predicting labor hours. In a preliminary effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved as the independent variable and has collected data for 36 moves in which the origin and destination were within the borough of Manhattan in New York City and in which the travel time was an insignificant portion of the hours worked. If the sum of squares Y is 1,513.32 and the sum of squares error is 176.22. What proportion of variation in labor hours is explained by the number of cubic feet moved? Hint: Provide answer accurate to 4 decimal places.

Hint: Provide your answer accurate to 2 decimal places.
Two pumps capable of delivering 100 hp to an agricultural application are being evaluated in a present economy study. The selected pump will only be utilized for one year, and it will have no market value at the end of the year. Pertinent data are summarized as given follows. If electric power costs $0.10 per kWh and the pump will be operated 4,000 hours per year, which pump should be chosen? Recall that 1 hp = 0.746 kW.
