Test the claim that the mean GPA of night students is larger than 2 at the .025 significance level.


The null and alternative hypothesis would be:




  • H0:p=0.5
    H1:p<>

  • H0:μ=2
    H1:μ≠2

  • H0:p=0.5
    H1:p≠0.5

  • H0:μ=2
    H1:μ>2

  • H0:μ=2
    H1:μ<>

  • H0:p=0.5
    H1:p>0.5







Based on a sample of 60 people, the sample mean GPA was 2.03 with a standard deviation of 0.06


The test statistic is  (to 3 decimals)


The critical value is  (to 3 decimals)


Based on this we
