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) - 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho versus H₁ (Type integers or decimals.

K 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 ▼ (Type integers or decimals. Do not round) Find the test statistic, Zo Find the P-value. 10, the sample size is Zo - (Round to two decimal places as needed) 5% of the population size, and the sample the requirements for testing the hypothesis satisfied > Show Transcribed Text ME P-value = (Round to three decimal places as needed) 3 c 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.
