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 2195 passenger cars in a particular region, 245 had only rear license plates.. Among 326 commercial trucks, 49 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. Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.

A) test the claim using a hypothesis test. Identify test statistic (round two decimal places) and p value (round three decimal places)
B) test the claim by constructing appropriate confidence interval.
Transcribed Image Text:b. 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.
O<P1 - P2 <O
