A regression was run to determine if there is a relationship between hours of TV watched per day (x) andthe number of sit-ups a person can do (y). The results were:= a+bxyb = -0.79a = 23.38r= 0.5396= -0.7346a. If a person watches 16 hours of television a day, predict how many sit-ups he can do.b. If a person can do 8 sit ups, predict how many hours of television a day they watch.hours

From the given information, y=a+bxb=-0.79a=23.38 Therefore, Y=23.38-0.79X
