A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y).

The results of the regression were:

y=ax+b

a=-0.719

b=37.806

r2=0.484416

r=-0.696

Use this to predict the number of situps a person who watches 11.5 hours of TV can do (to one decimal place)

Step 1

The given linear model is shown below:

Step 2

Substitute 11.5 for *x* in linear model to p...
