10.83 Duck hunting in populated areas faces opposition on the basis of safety and environmental issues. The San Luis Obispo Telegram-Tribune (June 18, 1991) reported the results of a survey to assess public opinion regarding duck hunting on Morro Bay (located along the central coast of
California). A random sample of 750 local residents in- cluded 560 who strongly opposed hunting on the bay. Does this sample provide sufficient evidence to conclude that the majority of local residents oppose hunting on Morro Bay? Test the relevant hypotheses using a = .01.
10.84 Seat belts help prevent injuries in automobile acci- dents, but they certainly don’t offer complete protection in extreme situations. A random sample of 319 front-seat oc- cupants involved in head-on collisions in a certain region resulted in 95 people who sustained no injuries (“Influenc- ing Factors on the Injury Severity of Restrained Front Seat Occupants in Car-to-Car Head-on Collisions,” Accident Analysis and Prevention [1995]: 143–150). Does this sug- gest that the true (population) proportion of uninjured oc- cupants exceeds .25? State and test the relevant hypothe- ses using a significance level of .05.
