A statistics instructor would like to know whether it is worthwhile to require students to do weekly homework assignments. For one section of the statistics course, homework is assigned, collected and graded each week. For another section, the same problems are suggested each week, but the students are not required to turn in their homework. At the end of the semester, all students take the same final exam. The score distribution for the two sections are as follows:   With Homework          12      15        17        5         10 No Homework             12      21        28        25        14          Do these data indicate a significant difference between the score distributions for students with homework versus students with no homework? Test at the 5% level of significance.
