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 0.32. Suppose a random sample of 112 traffic fatalities in a certain region results in 48 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) = 24.4 > 10, the sample size is less than 5% of the population size, and the sample the requirements for testing the hypothesis are satisfied is given to be random, (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho р 0.32 versus H₁: Р (Type integers or decimals. Do not round.) Find the test statistic, Zo- Zo 0.32 (Round to two decimal places as needed.) h
