2. For this problem, use the grade point averages given in the textbook, Chapter 3, end-of-chapter Problem 15, p. 72.

Give the scores the new name, GPA. For convenience the scores are repeated here.

Use SPSS to construct a histogram of the scores, with a normal curve superimposed on the histogram. Is the distribution symmetrical? If not, is it positively or negatively skewed? Is the distribution normally distributed?
