Using 20 observations, the following regression output is obtained from estimating y:A + + 2d d Coeff f Stat ror 3.40 0.50 3.00 -2.03 0.0593 0.75 4.75 5.08 0.0000 ntercept16.15 0.0002 2.54 -6.09 2.49 xd 3.32 0.0043 a. Compute y-hat for x 11 and d 1: then compute y-hat for x 11 and d0. (Round intermediate calculations to 4 decimal places and final answers to 2 decimal places.) hat x=11 and d = 1 x-11 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 No, since we do not reject the relevant null hypothesis b2. 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 No. since we reject the relevant null hypothesis No. since we do not reject the relevant null hypothesis Type here to search

Explanation / Answer

a) x = 11 and d = 1

y = 16.15 + 2.45 * 11 - 6.09 * 1 + 2.49 * 11

y = 64.4

b) x = 11, d = 0

y = 16.15 + 2.45 * 11

y = 43.1

c)When you perform a hypothesis test in statistics, a p-value helps you determine the significance of your results. ... The p-value is a number between 0 and 1 andinterpreted in the following way: A small p-value (typically 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis.

Here, p > alpha

Not significant

D option

d) Here, p < alpha

Significant

A option
