Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2108 passenger cars in a particular region, 240 had only rear license plates. Among 303 commercial trucks, 41 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.05 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. I a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. O A. Ho: P1 = P2 HP1 P2 OB. Ho: P1 P2 H:21 = P2 O C. Ho: P1 = P2 H1:21 > P2 OD. Ho: P1 = P2 H:P17 P2 Identify the test statistic (Type an integer or a decimal. Round to two decimal places as needed.) Identify the P-value. (Type an integer or a decimal. Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than Ho. There owners of passenger cars. b. Identify the confidence interval limits for the appropriate confidence interval. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. <py-P2< (Type integers or decimals. Round to three decimal places as needed.) sufficient evidence to support the Because the confidence interval 0, there a significant difference between the two proportions. There claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
