50. (Section 1) Rebecca and her father both graduated from the same high school. When her father looked at Rebecca's transcript, he noticed that her high school GPA (4.2)
was higher than his high school GPA (3.9). After letting Rebecca gloat for a minute, he
pointed out that there were no weighted grades when he went to school. To settle
their argument, they called the registrar at the school and got information about the
distribution of GPA in each of their graduation years. Who had a better GPA?
a. When Rebecca graduated, the distribution of GPA had a mean of 3.2 and a standard
deviation of 0.7. Calculate and interpret the 2-score for Rebecca's GPA.
