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

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 equals 0.1α=0.1

level of​ significance?
