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 0.35. Suppose a random sample of 108 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)=
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
Ho
▼ versus H₁ ▼

Determine the conclusion for this hypothesis test. Choose the correct answer below.
O A. Since P-value> a, do not reject the null hypothesis and conclude that there is not sufficient evidence that
the region has a higher proportion of traffic fatalities involving a positive BAC than the country
OB. Since P-value <a, reject the null hypothesis and conclude that there is sufficient evidence that the region
has a higher proportion of traffic fatalities involving a positive BAC than the country
OC. Since P-value> a, reject the null hypothesis and conclude that there is sufficient evidence that the region
has a higher proportion of traffic fatalities involving a positive BAC than the country.
OD. Since P-value <a, do not reject the null hypothesis and conclude that there is not sufficient evidence that
the region has a higher proportion of traffic fatalities involving a positive BAC than the country.
