Exhibit 12-2
Regression analysis was applied between sales data (in $1,000s) and advertising data (in $100s) and the following information was obtained.

Y with hat= 12 + 1.8x

n= 17
SSR = 225
SSE = 75
sb1= 0.2683

1. Refer to Exhibit 12-2. The critical F value at a = 0.05 is
a. 3.59
b. 3.68
c. 4.45
d. 4.54

2. Using = 0.05, the critical t value for testing the significance of the slope is
a. 1.753
b. 2.131
c. 1.746
d. 2.120
