Answer:
Step-by-step explanation:
Base on the scenario been described in the question, we can use the following method to solve the given problem
Test the claim at 5% level of significance.
0: − ≤ 0
: − > 0
Since the population standard deviations are known we can use z-distribution.
Test statistic is

= 2.14.
Critical value for 5% level of significance:
zcrit = 1.645.
We reject the null hypothesis at 5% level of significance because the test statistic = 2.14 is bigger than
critical value zcrit= 1.645. There is evidence to conclude that students in the California state university
system take on average longer to graduate, than students enrolled in private universities.
