Please help, whats the answer to part A?
Using 20 observations, the following regression output is obtained from estimating y= ?0 + ?|x + ?2d + ?3xd+ ? Standard Coefficients Error t Stat 4.15 3.95 p-value 0.0008 0.0000 0.0907 0.0171 Intercept 14.94 2.37 5.58 1.33 3.60 0.60 3.10 0.50 2.66 a. Compute y-hat for x- 10 and d1; then compute y-hat for x 10 and d 0. (Round intermediate calculations to 4 decimal places and final answers to 2 decimal places.) hat x-10 and d 1 x-10 and d 0 b-1. Is the dummy variable d significant at the 5% level? Yes, since we reject the relevant null hypothesis Yes, since we do not reject the relevant null hypothesis No, since we reject the relevant null hypothesis No, since we do not reject the relevant null hypothesis b-2. Is the interaction variables xd significant at the 5% level? Yes, since we reject the relevant null hypothesis 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 hypothesisExplanation / Answer
a) at x=10 and d=1 ; predicted value of y =14.94+10*2.37-1*5.58+10*1*1.33 =46.36
at x=10 and d=0 ; predicted value of y =14.94+10*2.37-0*5.58+10*0*1.33 =38.64
b-1)
no since we do not rejeect the relevent numm hypothesis
b-2)
Ys since we reject the null hypothesis
