At the end of classes professors are rated by their students on a scale of 1 (poor) to 5 (excellent). Students are also asked what course grades they expect, and these are coded as A = 4, B = 3, and so on. The data file Teacher Rating contains, for a random sample of 20 classes, ratings of professors, the average expected grades, and the numbers of students in the classes. The variables are defined in the data file. Compute the multiple regression of rating on expected grade and number of students, and write a report on your findings.
