Test the claim that the mean GPA of night students is smaller than 3.4 at the .005 significance level.

The null and alternative hypothesis would be:

H0:p=0.85H0:p=0.85
H1:p>0.85H1:p>0.85
H0:p=0.85H0:p=0.85
H1:p≠0.85H1:p≠0.85
H0:μ=3.4H0:μ=3.4
H1:μ≠3.4H1:μ≠3.4
H0:p=0.85H0:p=0.85
H1:p<0.85H1:p<0.85
H0:μ=3.4H0:μ=3.4
H1:μ>3.4H1:μ>3.4
H0:μ=3.4H0:μ=3.4
H1:μ<3.4H1:μ<3.4



The test is:

-left-tailed
-two-tailed
-right-tailed



Based on a sample of 20 people, the sample mean GPA was 3.35 with a standard deviation of 0.08

The test statistic is:  (to 2 decimals)

The critical value is:  (to 2 decimals)

Based on this we:

-Reject the null hypothesis

-Fail to reject the null hypothesis
