A regression was run to determine if there is a relationship between hours of TV watched per day ( ) and number of situps a person can do ( ). The results of the regression were: y = ax+b a = -1.213 b = 24.09 r2 = 0.451584 r = -0.672 Use this to predict the number of situps a person who watches 8 hour(s) of TV can do, and please round your answer to a whole number.

A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.972 b=30.194 r2=0.565504 r=-0.752 Use this to predict the number of situps a person who watches 8.5 hours of TV can do (to one decimal place)
