Question
In an effort to improve the mathematical skills of 15 students, a teacher provides a weekly 1-hour tutoring
session. A pre-test is given before the sessions and a post-test is given after. The results are shown here.
Test the claim that there was an increase in the scores. at a=0.01. You believe that the population is
normally distributed, but you do not know the standard deviation. When calculating difference use Post-
test minus Pre-test.
