Michael has a weighted high school GPA of 3.12. 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 3.57. 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.
With the understanding that both schools measure the same kind of ability, who has the higher GPA in comparison to their respective normal population of scores (that is, who has the highest percentile in his/her school)?
Kami
Michael
MIchael and Kami are tied
