Question

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 2148 passenger cars in a particular region,250 had only rear license plates. Among 315 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. H0: p1<p2 H1: p1 = p2

B. H0: p1= p2 H1: p1≠p2

C. H0: p1=p2 H1: p1< p2

D. H0: p1=p2 H1: p1>p2

Identify the test statistic. (Round to two decimal places as needed.)

Identify the P-value.

State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.

Identify the confidence interval limits for the appropriate confidence interval. 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.

__ < p1 - p2 < __ (Round to four decimals places as needed)

Because the confidence interval limits ____ (contain or do not contain)

there ___ (is or is not) a significant difference between the two proportions. There __ (is not or is) sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
