From the Histogram , Can Normality be assumed ? YES OR NO

Since the p-value is GREATER OR LESS than the significance level 0.05, the null hypothesis fails to be rejected or is rejected

Sufficient Or Insufficent evidence exists that the mean GPA is greater than 2.75

A school administrator believes that the mean class GPAs for a given course are higher than the preferred mean of 2.75 at a signicance level of 0.05, and checks a randomly chosen sample of 50 classes. Use Sheet 1 of the Excel le to create a histogram, and calculate E, the tstatistic, and the pvalue. From the histogram, can normality be assumed? E = Ex: 11234 i t = i P = 5 Since the pvalue is Pick than the signicance level 0.05, the null hypothesis Pick . Pick evidence exists that the mean GPA is greater than 2.75
