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 0.33. Suppose a random sample of 104 traffic fatalities in a certain region results in 46 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 (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho versus H: (Type integers or decimals. Do not round.) Find the test statistic, Zo- Zo= (Round to two decimal places as needed.) Find the P-value. P-value (Round to three decimal places as needed.) = satisfied. Determine the conclusion for this hypothesis test. Choose the correct answer below. O A. Since P-value a, reject the null hypothesis and conclude that there is sufficient evidence that the region has a higher proportion of traffic fatalities involving a positive BAC than the country. OC. Since P-value a, do not reject the null hypothesis and conclude that there is not sufficient evidence that the region has a higher proportion of traffic fatalities involving a positive BAC than the country.
