Step 1 :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 0.36. Suppose a random sample of 106 traffic fatalities in a certain region results in 52 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 $\alpha=0.05$ level of significance?
Step 2 :Because $n p_{0}\left(1-p_{0}\right)=24.4>10$, the sample size is less than $5 \%$ of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied.
Step 3 :The null and alternative hypotheses are: Null Hypothesis, $H_{0}$: $p = 0.36$ Alternative Hypothesis, $H_{1}$: $p > 0.36$
Step 4 :The final answer is: Null Hypothesis, $H_{0}$: $p = 0.36$ Alternative Hypothesis, $H_{1}$: $p > 0.36$
