Each minute of a personal call costs the agency $0. 50 in wasted wages. The agency decides to hire operators to monitor calls in order to attain the optimal number of personal calls (minimize total cost of personal calls). |Total minutes of personal | |Number of Operators |calls (per hour) | |0 |600 | |1 |480 | |2 |410 | |3 |370 | |4 |350 | 12If operators receive $25 an hour, how many operators should the agency hire? a. 0 b. 1 c. 2 d. 3 e. 4 3If operators receive $25 an hour, what is the minimum possible total cost of personal calls (per hour)? a. $460 b. $255 c. $120 d. $ 85 e. none of the above The next question refer to the following: A manager in charge of new product development can hire engineers and market researchers. The annual salary of an engineer is $40,000 while a market researcher receives $20,000. The marginal contribution of engineers and market researchers are: |Engineers (E) |Market Researchers (R) | |Worker |Additional Worker |Additional | | |New Products | |New Products | |1st |240 |1st |80 | |2nd |200 |2nd |70 | |3rd |160 |3rd |60 | |4th |100 |4th |50 | |5th |40 |5th |40 | 14How should a manager with an annual budget of $140,000, allocate this budget in order to maximize the number of new products developed? a. Hire one engineer and five market researchers b. Hire two engineers and three market researchers c. Hire three engineers and one market researcher d. Hire four engineers and four market researchers Answer the next question using the following marginal benefit and marginal cost functions for activity A: MB = 100 ( 5A MC = 20 + 3A 15The optimal level of A is a. 40 b. 30 c. 20 d. 10 e. 0 16The sample regression line a. hows the actual (or true) relation between the dependent and independent variables. b. is used to estimate the population regression line. c. connects the data points in a sample. d. is estimated by the population regression line. e. maximizes the sum of the squared differences between the data points in a sample and the sample regression line. 17To test whether the overall regression equation is statistically significant one uses a. the t-statistic. b. the R2-statistic. c. the F-statistic. d. the standard error statistic. The next question refer to the following: The linear regression equation, Y = a + bX, was estimated. The following computer printout was obtained:

The next question refer to the following: A firm is experiencing theft problems at its warehouse. A consultant to the firm believes that the dollar loss from theft each week (T) depends on the number of security guards (G) and on the unemployment rate in the county where the warehouse is located (U measured as a percent).

In order to test this hypothesis, the consultant estimated the regression equation T = a + bG + cU and obtained the following results: DEPENDENT VARIABLE: TR-SQUAREF-RATIOP-VALUE ON F OBSERVATIONS: 270. 779342. 380. 0001 PARAMETER STANDARD VARIABLE ESTIMATEERRORT-RATIOP-VALUE INTERCEPT5150. 431740. 722. 960. 0068 G- 480. 92130. 66- 3. 680. 0012 U211. 075. 02. 810. 0096 19Hiring one more guard per week will decrease the losses due to theft at the warehouse by _________ per week. a. $5,150 b. $211 c. $130 d. $480. 92 20If the p-value is 10%, then the a. level of significance is 10%. b. level of confidence is 90%. c. probability of a Type I error is 90%. d. both a and b e. all of the above
