**Hypothesis Testing and Significance Level****Problem Statement:**Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).- The test statistic in a left-tailed test is $ z = -2.05 $.**Options:**- A. **P-value:** 0.0202; **Conclusion:** reject the null hypothesis- B. **P-value:** 0.0404; **Conclusion:** reject the null hypothesis- C. **P-value:** 0.0453; **Conclusion:** fail to reject the null hypothesis- D. **P-value:** 0.4798; **Conclusion:** fail to reject the null hypothesis**Next Steps:**Select the correct P-value and conclusion using the standard 0.05 significance level.

Among 2073 passenger cars in a particular region, 222 had only rear license plates. Among 339 commercial trucks, 51 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 0.10 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.
