    12.59 A common belief among faculty is that teaching ratings are lower in large classes. Below are
    MINITAB results from a regression using Y = mean student evaluation of the professor and X =
    class size for 364 business school classes taught during the 2002-2003 academic year. Ratings are
    on a scale of 1 (lowest) to 5 (highest). (a) What do these regression results tell you about the relationship
    between class size and faculty ratings? (b) Is a bivariate model adequate? If not, suggest
    additional predictors to be considered.
