Help/ 604 2188784 qx3zzyz Start 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 , the t-statistic, and the p-value. From the histogram, can normality be assumed? Picky x = EX: 1.234 t = p Since the p-value is Pick . than the significance level 0.05, the null hypothesis Pick v evidence exists that the mean GPA is greater than 2.75.
