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 2115 passenger cars in a particular region, 243 had only rear license plates. Among 319 commercial trucks, 47 had only rear license plates.

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. I A. Ho , <P2 HP1 = P2 B. Ho P4-P2 Hy: PP2 OC Ho: P4" P2 He: P1 *P2 OD.
