The average grade point average (GPA) of undergraduate students in New York is normally distributed with a population mean of 2.5 and a population standard deviation of 0.4

(III) Above what GPA will the top 7% of the students be (i.e., compute the 93rd percentile): GPA (IV) If a sample of 36 students is taken, what is the probability that the sample mean GPA will be between 2.5 and 2.75?
