G 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 2008 passenger cars in a particular region, 221 had only rear license plates. Among 317 commercial trucks, 46 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. A. Upper H 0: p 1equalsp 2 Upper H 1: p 1less thanp 2 B. Upper H 0: p 1equalsp 2 Upper H 1: p 1greater thanp 2 C. Upper H 0: p 1equalsp 2 Upper H 1: p 1not equalsp 2 D. Upper H 0: p 1less thanp 2 Upper H 1: p 1equalsp 2
