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=a+bx b=-1.376 a=26.924 r²=0.855625 r=-0.925 Use this to predict the number of situps a person who watches 1 hours of TV can do.

When the difference between what we expect and what we observe in a study is usually large and cannot be attributed to chance, the findings is ______________.
