A regression was run to determine if there is a relationship between hours of tv watched per day (x) and the number of situps a person can do (y).The results of the regression were:y=ax+ba=−1.077b=30.98r2=0.7447 69r=−0.863Use this to predict the number of situps a person who watches 13.5 hours of TV can do.

The number of situps is: 16.4405

Step-by-step explanation:

Given

Required

Predict y when

In the result, we have:

This implies that:

To make prediction when

We have:

c. (3,2,6) is the answer.

0.02
