est the claim that the mean GPA of night students is significantly different than 2.4 at the 0.05 significance level. The test is based on a sample of 45 people, the sample mean GPA was 2.45 with a standard deviation of 0.04. The null and alternative hypothesis would be: H0:μ≤2.4 H1:μ>2.4 H0:μ=2.4 H1:μ≠2.4 H0:p≥0.6 H1:p<0.6 H0:p≤0.6 H1:p>0.6 H0:μ≥2.4 H1:μ<2.4 H0:p=0.6 H1:p≠0.6 The test is: right-tailed two-tailed left-tailed The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis

Hypothesis Test for a Population Mean
Test the claim that the mean GPA of night students is significantly different than 2.4 at the 0.05 significance level. The test is based on a sample of 45 people, the sample mean GPA was 2.45 with a standard deviation of 0.04.
The null and alternative hypothesis would be:
H0:μ≤2.4
H1:μ>2.4
H0:μ=2.4
H1:μ≠2.4
H0:p≥0.6
H1:p<0.6
H0:p≤0.6
H1:p>0.6
H0:μ≥2.4
H1:μ<2.4
H0:p=0.6
H1:p≠0.6
The test is:
right-tailed
two-tailed
left-tailed
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we:
- Reject the null hypothesis
- Fail to reject the null hypothesis
