t 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: p1p2 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.

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.
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.
