In a survey of 3031 adults, a poll asked people whether they smoked cigarettes and whether they always wear a seat belt in a car. The table shows the results of the survey. For each activity, define a success as finding an individual that participates in the hazardous activity. Complete parts (a) and (b). No Seat Belt Seat Belt (success) (failure) Smoke 56 431 (success) Do not smoke 349 2195 (failure) (a) Why is this a dependent sample? O A. Two questions where asked. O B. The same person answered both questions. O C. More than 5% of the population was surveyed. (b) Is there a significant difference in the proportion of individuals who smoke and the proportion of individuals that do not wear a seat belt? In other words, is there a significant difference between the proportion of individuals who engage in hazardous activities? Use the a = 0.10 level of significance. Let p, represent the proportion of individuals who smoke and p2 represent the proportion of individuals that do not wear a seat belt. What are the hypotheses for this test? Hnan.
