A regression was run to determine if there is a relationship between hours of TV watched per day (x)and the number of sit-ups a person can do (y). The results were:y = a+bxb = -0.89a = 23.19=0.4924-0.7017a. If a person watches 14 hours of television a day, predict how many sit-ups he can do.b. If a person can do 6 sit ups, predict how many hours of television a day they watch.hours2.

In this question we will use basic of algebra i.e solution by regression equation. We will simply…

Answered: y = a+bx %3D b = -0.89 a 23.19 r2 =…
