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=a+bx a=37.5 b=-1.319 r2=0.597529 r=-0.773 Assume the correlation is significant (p-value < α α ), and use this to predict the number of situps a person who watches 7.5 hours of TV can do (to one decimal place)
