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
