Using 20 observations, the following regression output is obtained from estimating y = 0 + 1x + 2d + 3xd + . |
Coefficients | Standard Error | t Stat | p-value | |
Intercept | 16.32 | 3.20 | 5.10 | 0.0001 |
x | 5.59 | 0.50 | 11.18 | 0.0000 |
d | 5.61 | 5.50 | 1.02 | 0.3229 |
xd | 3.51 | 0.54 | 6.50 | 0.0000 |
a. | Compute y-hat for x = 12 and d = 1; then compute y-hat for x = 12 and d = 0. (Round intermediate calculations to 4 decimal places and final answers to 2 decimal places.) |
y-hat | |
x = 12 and d = 1 | |
x = 12 and d = 0 | |
