# Consider A Scenario Where Two Classes Take The Same Exam And The Performance In

Consider a scenario where two classes take the same exam and the performance in these two classes is as follows: Class A is taught on Mondays and therefore represents the students who take weekday classes: the average grade is 82 points, the standard deviation is 11, and the number of students taking the exam is 80.Class B is taught on Saturdays and therefore represents the students who take weekend classes: the average grade is 87 points, the standard deviation is 8, and the number of students taking the exam is 90. We can assume that the standard deviations are those of the two populations.

Based on this, can we reject with a 90% level of significance the hypothesis that the average performance of the weekend students (Class B), exceeds that of the weekday students (Class A) by at least 10 points
