Expert Solution
Step 1
From the given information,
The regression equation is y=-0.985x+31.518.
Here, x represents the hours of TV watched per day and y represents the number of sit ups a person.
Given that the number of hours TV can do is 13.5. That is, x=13.5.
Substitute x=13.5 in the regression equation, y=-0.985x+31.518.
