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 = a + bx %3D a = 36.694 b = - 0.874 R %3D = 0.923521 a) Use this to predict the number of situps a person who watches 0.5 hours of TV can do (to 3 decimal places) b) What is the value of the correlation coefficient (to 3 decimal places) ?
