Use the traditional method of hypothesis testing to test the claim about the means of two populations. Assume that two dependent samples have been randomly selected from normally distributed populations (-4.6 and + 4.6). Five students took a math test before and after tutoring. Their scores are: Before- 69, 66, 78, 73, 75 After- 73, 75, 76, 76, 87 Using a 0.01 level of significance, test the claim that the tutoring has an effect on the math scores
