2. A
researcher is concerned with the possible effects of marital status on the
academic progress of college students. Do married students, with their extra
burden of family responsibilities, suffer academically as compared to unmarried
students? (Or: Is academic performance dependent on marital status?) A random
sample of 453 students is gathered, and each student is classified as either
married or unmarried, and –using GPA as a measure—as a good, average, or poor
student. Results are presented in the table below:
