Test the given claim about the means of two populations. Assume that two dependent samples have been
randomly selected from normally distributed populations. A test of abstract reasoning is given to a random
sample of students before and after they completed a formal logic course. The results are given below. At the
0.05 significance level, test the claim that the mean score is not affected by the course. Include your null and
alternative hypotheses, the test statistic, P-value or critical value(s), conclusion about the null hypothesis, and
conclusion about the claim in your answer. $$\begin{array} { | l l l l l l l l l l l | }
