A regression was run to determine if there is a relationship between hours of study per week (xx) and the final exam scores (yy). The results of the regression were: y=ax+b a=5.614 b=32.79 r2=0.808201 r=0.899 Use this to predict the final exam score of a student who studies 1 hours per week, and please round your answer to a whole number.
