A regression was run to determine if there is a relationship between hours of TV watched per day (x) an
number of situps a person can do (y).
The results of the regression were:
y=ax+b
a=-1.395
b=38.945
r²-0.393129
r=-0.627
Use this to predict the number of situps a person who watches 1.5 hours of TV can do (to one decimal
place)
