A regression was run to determine if there is a relationship between hours of TV watched per day, xx, and number of sit-ups, yy, a person can do in a minute. The results of the regression were: y=ax+b a=-0.873 b=23.593Use this to predict the number of sit-ups a person who watches 1111 hours of TV can do in a minute. Round to the nearest whole number.
