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


110

traffic fatalities in a certain region results in


49

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=0.05

level of​ significance?
