In a national survey college students were asked, "how often do you wear a seat belt when riding in a car driven by someone else? " the response frequencies appear in the table to the right. (a) construct a probability model for seat-belt use by a passenger. (b) would you consider it unusual to find a college student who never wears a seat belt when riding in a car driven by someone else? response frequencyfrequency never 142142 rarely 322322 sometimes 514514 most of the time 11641164 always 22812281 (a) complete the table below. response probability never 0.0320.032 (round to the nearest thousandth as needed.) rarely 0.0730.073 (round to the nearest thousandth as needed.) sometimes 0.1160.116 (round to the nearest thousandth as needed.) most of the time 0.2630.263 (round to the nearest thousandth as needed.) always 0.5160.516 (round to the nearest thousandth as needed.) (b) would you consider it unusual to find a college student who never wears a seat belt when riding in a car driven by someone else? a. yes, because p(never)less than< 0.05. b. no, because there were 142142 people in the survey who said they never wear their seat belt. c. no, because the probability of an unusual event is 0. d. yes, because 0.01less than< p(never)less than< 0.10.
