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: ŷ=ax+b a=-0.643 b=32.437 r?=0.570025 r=-0.755 Use this to predict the number of situps a person who watches 2 hours of TV can do (to one decimal place)

Question
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: ŷ=ax+b a=-0.643 b=32.437 r²=0.570025 r=-0.755 Use this to predict the number of situps a person who watches 2 hours of TV can do (to one decimal place)
