Test the claim that the mean GPA of night students is significantly different than 2.9 at the 0.2 significance level.
The null and alternative hypothesis would be:
H0:μ≤2.9
H1:μ>2.9
H1:μ>2.9
H0:p=0.725
H1:p≠0.725
H1:p≠0.725
H0:μ=2.9
H1:μ≠2.9
H1:μ≠2.9
H0:μ≥2.9
H1:μ<2.9
H1:μ<2.9
H0:p≥0.725
H1:p<0.725
H1:p<0.725
H0:p≤0.725
H1:p>0.725
H1:p>0.725
The test is:
left-tailed
right-tailed
two-tailed
Based on a sample of 75 people, the sample mean GPA was 2.85 with a standard deviation of 0.04
The test statistic is:?
The p-value is: ?
Based on this we:
- Reject the null hypothesis
- Fail to reject the null hypothesis
