A regression analysis was performed to determine if there is a relationship between hours of TV watched
per day (¤) and number of sit ups a person can do (y). The results of the regression were:
y=ax+b
a=-0.985
b=31.518

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.
