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 108 traffic fatalities in a certain region results in 45 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) for testing the hypothesis (Round to one decimal place as needed.) = 10, the sample size is satisfied. *** 5% of the population size, and the sample is given to not be random, the requirements can be reasonably assumed to be random, cannot be reasonably assumed to be random, is given to be random,
