Using 20 observations, the following regression output is obtained from estimating y= 0 + 1Pad + 3xd + Standard t Stat 4.40 5.25 -0.96 4.75 p-value 0.0004 0.0000 0.3513 0.0002 Coefficients Error Intercept 14.30 2.73 -3.60 3.80 3.25 0.52 3.75 0.80 xd Compute y-hat forx= 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.) a. at x= 12 and d= 1 x= 12 and d= 0 b-1, is the dummy variable d significant at the 5% level? O Yes, since we reject the relevant null hypothesis O Yes, since we do not reject the relevant null hypothesis O No, since we reject the relevant null hypothesis O No, since we do not reject the relevant null hypothesis b-2. Is the interaction variables xd significant at the 5% level? O Yes, since we reject the relevant null hypothesis O Yes, since we do not reject the relevant null hypothesis O No, since we reject the relevant null hypothesis O No, since we do not reject the relevant null hypothesis

Explanation / Answer

y = 14.3 + 2.73*x - 3.6*d + 3.8*xd a) yhat x=12 and d=1 =14.3+2.73*12-3.6*1+3.8*1*12 89.06 x=12 and d=0 =14.3+2.73*12-3.6*0+3.8*0*12 47.06 b1) No since we don’t reject relevant null hypothesis with t = -0.96 and p-value > 0.05, I fail to rject ho b2) yes, since we reject relevant null hypothesis with t = 4.75 and p-value < 0.05, I rject ho
