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 2126 passenger cars in a particular region, 228 had only rear license plates. Among 331 commercial 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. 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. O A. Ho: P1 = P2 H1: P1 P2 O D. Ho: P1 < P2 H1: P1 = P2 Identify the test…
An institute conducted a clinical trial of its methods for gender selection. The results showed that 187 of 338 babies born to parents using a specific gender-selection method were boys. Use the sign test and a 0.01 significance level to test the claim that the method has no effect on the likelihood of a boy. Let p denote the population proportion of baby boys. Ignore the possibility of the method decreasing the likelihood of a boy. What are the null and alternative hypotheses? OA. Ho:p>0.5 H₁: p=0.5 OC. Ho: p=0.5 H₁: p20.5 B. Ho: p=0.5 H₁: p > 0.5 D. Ho: p=0.5 H₁: p=0.5 Find the test statistic. Test statistic = (Round to two decimal places as needed.)

a) Identify the variables and state the null and alternative hypotheses of a chi-squared test of independence. b) Find the expected count for cell (1, 1) and cell (2, 3) (that is, for cells (Lower income, Essential) and (Middle income, Not too important))
(d) Based on your answer to part (c), choose what can be concluded, at the significance level of0.05, about the claim in the university report. Since the value of the test statistic is in the rejection region, the null hypothesis is rejected. Therefore, there is sufficient evidence to reject the claim that the35%of students will find a partner the first time they use the website. Since the value of the test statistic is in the rejection region, the null hypothesis is not rejected.

A survey of 200 people was taken to determine whether distance from voting center was related to the likelihood of voting. Based on these results, does it appear that these two variables are related at the 10% level of significance?
Write out the null and alternative hypotheses (making sure that your notation is understandable) and the distribution of the test statistic (but not the test statistic itself) used to address these questions.
