College students attitudes toward parents. Researchers at the University of South Alabama compared the attitudes of male college students toward their fathers with their attitudes toward their mothers (Journal of Genetic Psychology, March 1998). Each of a sample of 13 males was asked to complete the following statement about each of their parents: My relationship with my father (mother) can best be described as: (1) awful, (2) poor, (3) average, (4) good, or (5) great. The following data were obtained:

(a) Specify the appropriate hypotheses for testing whether male students' attitudes toward their fathers differ from their attitudes toward their mothers, on average.

(b) Conduct the test of part a at α = .05. Interpret the results in the context of the problem.
