Exercises for Comparison of Means
Using the teaching ratings data, answer the following questions:
- Determine the mean and standard deviation for course evaluations for minority and non-minority instructors. Determine whether the instructors belonging to minority groups are more or less likely to obtain a course evaluation of 4.1 or higher.
- Determine the mean and standard deviation for course evaluations for upper- and lower-level courses. Determine whether the probability of obtaining a below-average course evaluation is higher for lower-level courses. Use 3.999 as the average course evaluation.
- Determine whether tenured professors receive above-average course evaluations.
