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

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=bx+ay^=bx+a b=0.726b=-0.726 a=34.563a=34.563 R2=0.64R2=0.64 a) Use this to predict the number of situps a person who watches 13 hours of TV can do (to 3 decimal places) b) What is the value of the correlation coefficient (to 3 decimal places)
