Question:
Consider the following data for a dependent variable and two independent variables, x1 and x2.
x1 | x2 | Y | |
29 | 12 | 94 | |
46 | 10 | 108 | |
24 | 18 | 112 | |
50 | 16 | 178 | |
41 | 5 | 95 | |
51 | 19 | 176 | |
75 | 8 | 170 | |
37 | 12 | 118 | |
60 | 13 | 143 | |
77 | 17 | 212 |
The estimated regression equation for these data is y= -15.40 +1.91x1 +4.82x2
Here SST = 15,262.4, SSR = 14,164.5, sb1 = 0l2356, and sb2 = 0.9187
a. Test for a significant relationship among x1, x2, and y. Use a = .05.
F = ???
b. Is B1 significant? Use a =0.05
tB1= ???
c. Is B2 significant? Use a =0.05
tB2= ???
