Answer #1

A multiple regression model has the form

y-estimeted =11+6X+12W

Here W is constant therefore change in x make expected change in Y using x only not W.

So as X increases by 1 unit. So expected change in y increases is coefficient of X because W is constant.

answer: increase by 6 units.
