Since the p-value is (greater/less) than the significance level 0.05, the null hypothesis (fails to be rejected/is rejected)

(sufficient/insufficient) evidence exists that the mean GPA is greater than 2.75.

Jump to level 1 Use Sheet 1 of the Excel file to answer the following questions. A school administrator believes that the mean class GPAs for a given course are higher than the preferred mean of 2.75 at a significance level of 0.05, and checks a randomly chosen sample of 50 classes. Create a histogram, and calculate a, the t-statistic, and the p-value. From the histogram, can normality be assumed? Yes 2 = EX: 1.234 t p = Since the p-value is Pick than the significance level 0.05, the null hypothesis Pick Pick evidence exists that the mean GPA is greater than 2.75.
