Question

Below you are given a partial computer output based on a sample of 16 observations Coefficient Standard Error Constant 12.924 4.425 X_1 -3.682 2.630 X_2 45.216 12.560 Refer to Exhibit 13-6. The interpretation of the coefficient of X_1 is that a. a one unit change in X_1 will lead to a 3.682 unit decrease in Y b. a one unit increase in X_1 will lead to a 3.682 unit decrease in Y when all other variables are held constant c. a one unit increase in X_1 will lead to a 3.682 unit decrease in X_2 when all other variables are held constant d. It is impossible to interpret the coefficient Refer to Exhibit 13-6 The test statistic used to determine if there is a relationship between X_2 and y a. -1.4 b. 0.2 c. 3.60 d. 5

Explanation / Answer

10) here to test if relationship exist b/w X2 and y:

test stat =(b2-0)/std error =45.216/12.560=3.6

therefore option C is correct
