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 0.37.

Suppose a random sample of 104 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 equals 0.05level of​ significance?

a) what are the null and alternative hypothesis?

b) z statistic

c) find the p-value
