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 2050 passenger cars in a particular region, 230 had only rear license plates. Among 382 commercial trucks, 57 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 0.01 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. 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. OA. Ho: P₁ = P2 H₁: P₁ P2 OB. Ho: P1 = P2 H₁: P₁ P2 OC. Ho: P1 = P2 H₁: P₁ P2 OD. Ho: P₁ P2 H₁: P₁ P2 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (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.
