Question

Test the claim that the mean GPA of night students is larger than 2.3 at the .025 significance level.
The null and alternative hypothesis would be:
Но : р — 2.3 Но:н — 2.3 Но:р %3D 0.575 Но: д —— 2.3 Но:р %3D 0.575 Но:р 3 0.575
H:р + 2.3 Hi:p<2.3 Ні:р < 0.575 H:д > 2.3 Н:р#0.575 H:р> 0.575
The test is:
left-tailed right-tailed two-tailed
Based on a sample of 65 people, the sample mean GPA was 2.34 with a standard deviation of 0.06
The test statistic is:
(to 2 decimals)
The critical value is:
(to 2 decimals)
Based on this we:
O Fail to reject the null hypothesis
O Reject the null hypothesis
