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: ý = bx + a b = - 1.263 23.495 R 0.480249 %3D a) Use this to predict the number of situps a person who watches 14 hours of TV can do (to 3 decimal places) b) What is the value of the correlation coefficient (to 3 decimal places) ?
