**Hypothesis Testing: License Plate Law Compliance for Trucks and Cars****Problem Statement:**Test the given claim by identifying the null hypothesis, alternative hypothesis, test statistic, and P-value. Conclude about the null hypothesis and address the original claim based on a significance level of 0.01. The hypothesis is that commercial trucks violate laws requiring front license plates at a higher rate than passenger cars.**Sample Data:**- Among 2126 passenger cars, 228 had only rear license plates.- Among 331 commercial trucks, 48 had only rear license plates.**Steps:****a. Null and Alternative Hypotheses:**Identify hypotheses by defining Population 1 as passenger cars and Population 2 as commercial trucks.- \( H_0: p_1 = p_2 \) - \( H_1: p_1 < p_2 \)"Success" is defined as a vehicle having only a rear license plate.**b. Test Statistic:**Identify the test statistic.- (Round to three decimal places as needed.)**c. P-value:**Identify the P-value.- (Round to three decimal places as needed.)**Conclusion on Null Hypothesis:**State the conclusion concerning the null hypothesis and its implications for the original claim.- **A.** Reject \( H_0 \): Support exists for the claim that trucks violate front license plate laws more than passenger cars.- **B.** Reject \( H_0 \): Insufficient evidence to support the claim.- **C.** Fail to reject \( H_0 \): Support exists for the claim.- **D.** Fail to reject \( H_0 \): Insufficient evidence for the claim.**d. Confidence Interval:**Identify the confidence interval limits for comparison.- \( p_1 - p_2 = \)- (Round to four decimal places as needed.)**Graphical Explanation:**No graphs or diagrams are present in the text.

Identify the null hypothesis, altenative 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 2126 passenger cars in a particular region, 228 had only rear license plates. Among 331 commercia trucks, 48 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.

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 2074 passenger cars in a particular region, 229 had only rear license plates. Among 359 commercial trucks, 55 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 regional planner obtains random samples of home costs from four Michigan counties. Suppose these home costs are normally distributed in each county and that home prices within each county vary about the same amount. What test should the planner use to learn if the differences in home cost by county are significant? State the null and alternative hypothesis Provide the name of the hypothesis testing method and explain why it is appropriate.
Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1708 people and found that 544 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced.a) Identify the null and alternative hypotheses?H0H0: H1H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance level.d) Calculate your test statistic (Use ˆpp^ rounded to 4 decimal places). Write the result below, and round your test statistic to 4 decimal places.e) Calculate your p-value. Write the result below, rounded to four decimal places.f) Do you reject the null hypothesis? We reject the null hypothesis, since the p-value is less than the significance level. We reject the…
Random digit dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differ from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old. Here’s what the Pew survey found about how these people describe their political party affiliation. State the Null and Alternative Hypotheses.
4. Researchers believe that men are more physically aggressive than women. To test this, researchers ask 20 participants (10 male, 10 female) to rate how aggressive they are on a scale from 1 to 10. Their scores are listed below. Conduct all six steps of hypothesis testing (use p=.05). Be sure to label all six steps. Also, include a concluding statement (which should include the effect size).
