Question
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=-1.116
b=38.397
r²-0.687241
r=-0.829
Use this to predict the number of situps a person who watches 7 hours of TV can do (to one decimal
place)
