A regression was run to determine if there is a relationship between hours of study per week (x) and the final exam scores (y). The results of the regression were: y=ax+b a=5.704 b=24.02 r2=0.436921 r=0.661 Use this to predict the final exam score of a student who studies 9 hours per week, and please round your answer to a whole number.
