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:y = a+bxb = -0.89a = 23.49r² = 0.6519r = -0.8074a. If a person watches 7 hours of television a day, predict how many sit-ups he can do.b. If a person can do 4 sit ups, predict how many hours of television a day they watch.hours

y = a+bx b = -0.89 a = 23.49 r2 = 0.6519 r = -0.8074
