Question

3. Mr. Smith Claims that students at Bamfield College of Aeronautic have a higher grade point average that those who attend who attend the Aviation College in Mar del Plata. The information below was collected at the two higher education institutions. Is there sufficient proof to reject Mr. Smith claim? Use alpha of 0.05 to test the claim. Assuming that the populations are normally distributed, samples are independent, and the variances are unequal.

Mar Del Plata Bamfield

Sample size = 17 Sample size = 16

Sample SD= 0.70 Sample SD= 0.72

Sample mean = 2.96 Sample mean = 3.04

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
