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 0.35. Suppose a random sample of 106 trafic fatalities in a certain region results in 50 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 = 0.01 level of significance? Because npo (1-Po) =D 10, the sample size is 5% of the population size, and the sample satisfied. the requirements for testing the hypothesis (Round to one decimal place as needed.)

Question
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 0.35. Suppose a random sample of 106 traffic fatalities in a certain region results in 50 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 = 0.01 level of significance?
Because npo (1- Po)
10, the sample size is
5% of the population size, and the sample
the requirements for testing the hypothesis
satisfied.
(Round to one decimal place as needed.)
