Question
How do I use this to predict the number of situps a person who watches 7.5 hours of TV can do (to one decimal place)
Transcribed Image Text: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=-1.112
b=38.481
r²-0.904401
r=-0.951
