Question: The owners of the Prescott Motor Company have been offered a chance to participate in a special study to find out if the AMCC (Armenian Motor Car Company) puts really annoying seatbelt reminders on its " Super Cruser 750 " that more people will in fact " buckle up ". The AMC officials point to a " national study " of 2,154 Armenian drivers that found the following: 74 percent of the drivers of the 950 cars that were equipped with the really annoying seatbelt reminders fastened their seatbelt within 5 minutes of the annoying sound that was similar to an Armenian hogwart in heat . (An unknown number bailed out and ran screaming into the nearest pond infested with poisoness snakes [hiss] and alligators [chomp].) But, only 61 percent of the drivers of the 1,204 cars equipped with the annoying sound that cut off after 10 seconds actually wore their seatbelts.

1. Write the null and research hypothesis for this study.
2. Using a 0.05 level of significance test the hypothesis that the cars with the longer reminder system increased seatbelt usage?
3. For 5 extra credit points, what can we do to increase the use of seatbelts and decrease the number of cell phone talkers and people texting while driving – make your answers believable.
