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 0.33. Suppose a random sample of 109 traffic fatalities in a certain region results in 45 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-P) = 24.1 > 10, the sample size is less than 5% of the population size, and the sample (Round to one decimal place as needed.) What are the null and alternative hypotheses? H₂: P = 0.33 versus H₁: p > 0.33 (Type integers or decimals. Do not round.) Find the test statistic, Zo Zo = (Round to two decimal places as needed.) is given to be random, ▼ the requirements for testing the hypothesis are satisfied.

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 0.33. Suppose a random sample of 109 traffic fatalities in a certain region results in 45 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 = 0.01 level of significance? Because npo (1-Po) = 24.1 > 10, the sample size is less than 5% of the population size, and the sample (Round to one decimal place as needed.) What are the null and alternative hypotheses? = 0.33 versus H₁: P > 0.33 Ho: P (Type integers or decimals. Do not round.) Find the test statistic, Zo. Zo = (Round to two decimal places as needed.) C is given to be random, the requirements for testing the hypothesis are satisfied.

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p=0.62 versus H₁: p<0.62 n = 150, x=84, a = 0.05 Is npo (1-Po) 21 Yes No > 10? Use technology to find the P-value. P-value = (Round to three decimal places as needed.)
