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 = alpha + bG + cU and obtained the following results: Dependent variable: T R-square
Observations: 27 0,7793
Variable parameter estimate p-value
Intercept 5150.43 0.0068
G -480.92 0.0012
