For a marketing class term project, Bob is investigating whether college seniors eat less frequently in fast-food chains than college freshmen. He asked 11 freshmen and 11 seniors to keep track of how many times they ate in a fast-food restaurant during the month of October. Assuming equal variances, can you conclude that the mean is significantly smaller for college seniors at the 5 percent level of significance? Seniors Freshmen 10            16 5               9 19            16 15            14 5              18 10            10 18            19 8              15 20             9 7              17 8              20
