Test the claim that the mean GPA of night students is significantly different than 2.5 at the 0.1 significance level. The null and alternative hypothesis would be: Ho: u 2 2.5 Ho:p <0.625 Ho:p 2 0.625 Ho:p 0.625 Ho:u < 2.5 Ho:p=2.5 H1:p < 2.5 H1:p > 0.625 H1:p< 0.625 H:p+ 0.625 H1:µ > 2.5 H1:p + 2.5 %3D The test is: left-tailed two-tailed right-tailed Based on a sample of 60 people, the sample mean GPA was 2.47 with a standard deviation of 0.07 The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis

This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 62.5. O There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 62.5. O The sample data support the claim that the population mean is greater than 62.5. O There is not sufficient sample evidence to support the claim that the population mean is greater than 62.5.
