3. The scores of individual students on a national test
have a normal distribution with mean 18.6 and
standard deviation 5.9. At Federico Ramos Rural High
School, 76 students took the test. If the scores at this
school have the same distribution as national scores,
what are the mean and standard deviation of the
sample mean for 76 students?
