(a) Find the value of k.
(b) Find the probability that a GPA exceeds 3 .
(c) Find the probability that a GPA is within 0.25 of 3 .
(d) Find the probability that a GPA differs from 3 by more than 0.5
Therefore p(2.5<x<3.5)=1/2=0.5

The grade point averages (GPAs) of a large population of college
students are approximately normally distributed with mean 2.5 and
standard deviation 0.7. If students possessing a GPA less than 1.75
are dropped from college, what percentage of the students will be
dropped? (Round your answer to two decimal places.)

A researcher wanted to test the claim that members of college
sororities have grade point averages (GPA) above the mean GPA of
2.64 for all college students. She collected a random sample of 50
members of college sororities that had a mean GPA of 2.82. It is
known that the population standard deviation for GPA is 0.90.
Conduct a hypothesis test for this situation at the 0.05 level of
significance and indicate what the researcher should conclude.
