Exercise 3
The data in the table represent the "Exam Scores" for two random samples of students. The first group of n1 = 6 students were under active-learning course, and the second group of n2 = 6 students were under traditional lecturing. Note that the standard deviations in the Active group is s1= 3.43 and in the Traditional group is s2 = 3.03.

Given in the table are the course evaluation scores for random
samples of male professors and female professors. Assume that the
two samples are selected from normal distributed populations and do
not assume that the population standard deviations are equal. Use
0.05 significance level to test the claim that the male professors
and female professors course evaluation scores are from the
population with the same mean. Let the male professor as the first
population.
