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=-1.271
b=39.101
²-0.407044
r=-0.638
Assume the correlation is significant, and use this to predict the number of situps a person who watches 14
hours of TV can do (to one decimal place)
