Question
A regression was run to determine if there is a relationship between hours of tv watched per day (x) and number of sit-ups a person can do (y)
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=-1.19
b=31.125
r²=0.829921
r=-0.911
Use this to predict the number of situps a person who watches 12 hours of TV can do (to one decimal place)
