GPA is approximately normally distributed for all students that have been accepted to UCLA. The average gpa is 4.0 with standard deviation of .2.

a) Between what 2 gpa's are considered normal for being accepted at UCLA.

b) 50 students were sampled and asked, "what is your gpa?" Calculate the standard deviation for the sampling distribution. Calculate the probability the mean is 3.95 or lower.
