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 b=-1.161 a=38.513 r²=0.915849 r=-0.957 Use this to predict the number of situps a person who watches 11.5 hours of TV can do. Round to one decimal place.
