Answer 1

Answer #1

(a) it tells that if there is a unit change in variable X1 then Y will change by beta1 unit. In other words it is slope of Y and X1 graph.

k- Xi yel tpe 2 꺼치 ㄧㄒㄧ xn--) プ-IN mahnx 2 nxn 12 EX に! Some us x; at the end we have found the same normal equation as in simple linear regression. Thus we can solve it to get the same estimate as of simple linear regression model for p=2
