Question
Test the claim that the mean GPA of night students is larger than 3.1 at the 0.10 significance level.
The null and alternative hypothesis would be:
- H0:p=0.775H0:p=0.775
H1:p≠0.775H1:p≠0.775 - H0:p=0.775H0:p=0.775
H1:p>0.775H1:p>0.775 - H0:μ=3.1H0:μ=3.1
H1:μ>3.1H1:μ>3.1
- H0:μ=3.1H0:μ=3.1
H1:μ<3.1H1:μ<3.1 - H0:p=0.775H0:p=0.775
H1:p<0.775H1:p<0.775 - H0:μ=3.1H0:μ=3.1
H1:μ≠3.1H1:μ≠3.1
The test is:
- right-tailed
- two-tailed
- left-tailed
Based on a sample of 75 people, the sample mean GPA was 3.14 with a standard deviation of 0.03
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we
- fail to reject the null hypothesis.
- reject the null hypothesis.
