Test the claim that the mean GPA of night students is larger 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

Based on a sample of 75 people, the sample mean GPA was 3.43 with a standard deviation of 0.02

The test statistic is (to 3 decimals)

The critical value is (to 3 decimals)

Based on this we

fail to reject the null hypothesis
reject the null hypothesis
