The article "Impacts of On-Campus and Off-Campus Work on First-Year Cognitive Outcomes" reported on a study in which y= spring math comprehension score was regressed against X previous fall test score, X2 previous fall academic motivation, X3= age, x4 number of credit hours, X5= residence (1 if on campus, 0 otherwise), X6 hours worked on campus, and x7= hours worked off campus. The sample size was n =210, and R2=0.543. Test to see whether there is a useful linear relationship between y and at least one of the predictors. (12.5)
