Choose the correct decision and summary based on the p-value.
Do not reject H0. There is not enough evidence that the mean GPA of night students is different than the mean GPA of day students.Two random samples are taken from private and public universities (out-of-state tuition) around the nation. The yearly tuition is recorded from each sample and the results can be found below. Test to see if the mean out-of-state tuition for private institutions is statistically significantly higher than public institutions. Assume unequal variances. Use a 1% level of significance.
