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 = b x + a b = − 1.374 a = 39.084 R2 = 0.950625 a) Use this to predict the number of situps a person who watches 10.5 hours of TV can do b) What is the value of the correlation coefficient

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 = b x + a

b = − 1.374

a = 39.084

R2 = 0.950625

a) Use this to predict the number of situps a person who watches 10.5 hours of TV can do

b) What is the value of the correlation coefficient
