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 0.38. Suppose a random sample of 112 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 α = 0.1 level of significance? Because npo (1-Po) = (Round to one decimal place as needed.) What are the null and alternative hypotheses? 10, the sample size is Ho: versus H₁: (Type integers or decimals. Do not round.) Find the test statistic, Zo. Find the P-value. P-value = Zo (Round to two decimal places as needed.) = the requirements for testing the hypothesis 5% of the population size, and the sample satisfied. (Round to three decimal places as needed.)
