Question:

An Internet provider wondered if its cable Internet customers were significantly more satisfied with one or the other of its two packages-free e-mail or free basic TV. The company surveyed customers currently receiving free e-mail with their cable Internet and customers currently receiving free basic TV with their cable Internet. Satisfaction scores ranged from 1 to 10 based on answers to the survey questions. Now let's suppose that the company did not survey equal numbers of customers receiving free e-mail versus free basic TV. For illustrative purposes, I have dropped the last four free basic TV cases from that previous example, leaving 12 free e-mail customers and 8 free basic TV customers. Here are the scores. Conduct a two-tailed t test at the .05 a level. Are customers significantly more satisfied with one package or the other?
