According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.34. Suppose a random sample of 105 traffic fatalities in a certain region results in 47 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the a = 0.05 level of significance? Because npo (1- Po) = V 10, the sample size is V 5% of the population size, and the sample V the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)
