Can Normality be assumed ? YES OR NO

Solve for X. T and P

Since the P value is GREATER OR LESS? , the Null Hypothesis FAILS TO BE REJECTED ? IS REJECTED ?

SUFFICIENT OR INSUFFICENT evidence exists

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? Pick 5 = Ex: 1.234 C t = i p = 3 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
