Test the claim that the mean GPA of night students is larger
than 2.1 at the .005 significance level.
The null and alternative hypothesis would be:
A. H0:p=0.525 H1:p≠0.525
B. H0:μ=2.1 H1:μ>2.1
C. H0:μ=2.1 H1:μ≠2.1
D. H0:p=0.525 H1:p<0.525
E. H0:p=0.525 H1:p>0.525
F. H0:μ=2.1 H1:μ<2.1
Based on a sample of 35 people, the sample mean GPA was 2.12 with a
standard deviation of 0.04
The test statistic is (to 3 decimals) _______
The critical value is (to 3 decimals) _______
Based on this we
A. fail to reject the null hypothesis
B. reject the null hypothesis
than 2.1 at the .005 significance level.
