A regression was run to determine if there is a relationship

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:

Use this to predict the number of situps a person who watches 4.5 hours of TV can do.

Solution

y = a+bx

Or y =38.665+0.75x

x= 4.5

Plug in this value

y = 38.665+0.75(4.5)

= 38.665+3.375

= 42.030
