A writing test is given to incoming freshman at a state university before and after they complete a required class on introductory writing. Scores are between 0 and 50 with a higher score indicating that the student has a more positive attitude toward writing. The test scores for a random sample of 15 freshman before and after they completed the introductory writing course are given below. Conduct a hypothesis test to see whether the writing class helped improve the students’ attitudes about writing. Use a significance level of 0.05.    Before 35 5 40 18 25 24 46 20 8 22 47 12 24 3 49 After 37 5 37 19 31 28 48 11 11 25 43 16 20 7 48  Hypothesis test needed
