Test the claim that the mean GPA of night students is smaller 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
H1:p>0.85H1:p>0.85
H0:p=0.85H0:p=0.85
H1:p≠0.85H1:p≠0.85
H1:p≠0.85H1:p≠0.85
H0:μ=3.4H0:μ=3.4
H1:μ≠3.4H1:μ≠3.4
H1:μ≠3.4H1:μ≠3.4
H0:p=0.85H0:p=0.85
H1:p<0.85H1:p<0.85
H1:p<0.85H1:p<0.85
H0:μ=3.4H0:μ=3.4
H1:μ>3.4H1:μ>3.4
H1:μ>3.4H1:μ>3.4
H0:μ=3.4H0:μ=3.4
H1:μ<3.4H1:μ<3.4
H1:μ<3.4H1:μ<3.4
The test is:
-left-tailed
-two-tailed
-right-tailed
Based on a sample of 20 people, the sample mean GPA was 3.35 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:
-Reject the null hypothesis
-Fail to reject the null hypothesis
