Question

Find z0 and the P-value 

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.
