Michael has a weighted high school GPA of 3.15. Assume that the distribution of GPA’s in his school is normally distributed with a mean of 2.7 and a standard deviation of 0.55. Kami’s high school uses unweighted GPA’s, and she has a GPA of 3.54. Assume that the distribution of GPA’s in her school is normally distributed with a mean of 2.65 and a standard deviation of 0.45.
