Test the claim that the mean GPA of night students is smaller than 2.9 at the 0.01 significance level.

The null and alternative hypothesis would be:

H0:p=0.725

H1:p≠0.725

H0:μ≥2.9

H1:μ<2.9

H0:p≤0.725

H1:p>0.725

H0:p≥0.725

H1:p<0.725

H0:μ=2.9

H1:μ≠2.9

H0:μ≤2.9

H1:μ>2.9

The test is:

left-tailed right-tailed two-tailed

Based on a sample of 80 people, the sample mean GPA was 2.85 with a standard deviation of 0.07

The test statistic is: ___________________ (to 2 decimals)

The p-value is:______________________ (to 2 decimals)
