Question

100%

A regression was run to determine if there is a relationship between hours of TV watched per day, x, and
number of sit-ups, y, a person can do in a minute.
The results of the regression were:
y=ax+b
a=-1.255
b=21.239
Use this to predict the number of sit-ups a person who watches 11.5 hours of TV can do in a minute. Round
to the nearest whole number.
