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.)
