Test the claim that the mean GPA of night students is smaller than 3 at the .05 significance level.

The null and alternative hypothesis would be:

H0:p=0.75
H1:p≠0.75

H0:μ=3
H1:μ>3

H0:p=0.75
H1:p>0.75

H0:μ=3
H1:μ<3

H0:p=0.75
H1:p<0.75

H0:μ=3
H1:μ≠3



The test is:

left-tailed

right-tailed

two-tailed



Based on a sample of 35 people, the sample mean GPA was 2.97 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:

  • Fail to reject the null hypothesis
  • Reject the null hypothesis
