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 finalconclusion that addresses the original claim. Among 2164 passenger cars in a particular region, 250 had only rear license plates. Among 324 commercial trucks, 44 hadonly rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passengercars. Use a 0.01 significance level to test that hypothesis.a.

A politician claims that the mean salary for managers in his state is more than the national mean, $84,000. Assume the the population is normally distributed and the population standard deviation is $7700. The salaries (in dollars) for a random sample of 30 managers in the state are listed. At a = 0.01, is there enough evidence to support the claim?
