Economists theorize that the recent recession has affected men more than women because men are typically employed in industries that have been hit hardest by the recession. Women, on the other hand, are typically employed in serviceswhich are considered more recession resistant. A sample of 160 men and a sample of 145 women were drawn. In those samples, 20 men were unemployed, and 13 of the women were unemployed. Complete parts a and b below....D-a.

The recidivism rate for convicted sex offenders is 15%. A warden suspects that this percent is different if the sex offender is also a drug addict. Of the 386 convicted sex offenders who were also drug addicts, 46 of them became repeat offenders. What can be concluded at the αα = 0.10 level of significance? For this study, we should use The null and alternative hypotheses would be: Ho: (please enter a decimal) H1: (Please enter a decimal) The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly different from 15% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of convicted sex offender drug addicts who become repeat offenders is different from 15%.…
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 2010 passenger cars in a particular region, 234 had only rear license plates. Among 314 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 0.10 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. 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<…

A study suggests that the 25% of 25 year olds have gotten married. You believe that this is incorrect and decide to collect your own sample for a hypothesis test. From a random sample of 25 year olds in census data with size 776, you find that 24% of them are married. A friend of yours offers to help you with setting up the hypothesis test and comes up with the following hypotheses. Indicate any errors you see. H0:^p=0.24 HA:^p≠0.24

Consolidated Power, a large electric power utility, has just built a modern nuclear power plant. This plant discharges waste water that is allowed to flow into the Atlantic Ocean. The Environmental Protection Agency (EPA) has ordered that the waste water may not be excessively warm so that thermal pollution of the marine environment near the plant can be avoided. Because of this order, the waste water is allowed to cool in specially constructed ponds and is then released into the ocean. This cooling system works properly if the mean temperature of waste water discharged is 60°F or cooler. Consolidated Power is required to monitor the temperature of the waste water. A sample of 100 temperature readings will be obtained each day, and if the sample results cast a substantial amount of doubt on the hypothesis that the cooling system is working properly (the mean temperature of waste water discharged is 60°F or cooler), then the plant must be shut down and appropriate actions must be taken…
١٣.Value of test statistic Chi square is 6.435 and critical value of Chi square from the table is 6.345; thus we will reject the null hypothesis (H0). Select one: True False
Consider testing H,: B1 = 0 and B2 = 0 under the assumption that the individual t- statistics from the individual hypothesis tests are independent of one another. Consider the "one at a time" test, which tests the joint hypothesis by combing the individual null hypotheses using the individual t-statistics. Solve for the size of the "one at a time" test when the significance level a = 0.1. %3D
A hypothesis test will be conducted and after summarinzing the data, the observed test statistic is z = 1.9. Explain how much evidence we have against the null hypothesis (H0) and for the alternative hypothesis (Ha) in each of the following sets of hypotheses: Explain the reason that the answer differs depending on the chosen alternative hypothesis.
Suppose there is a claim that a certain population has a mean, µ, that is different than 7. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.05 level of significance. To start this test, you write the null hypothesis H, and the alternative hypothesis H, as follows. Hoi u= 7 H: u =7 Suppose you also know the following information. The critical values are - 1.960 and 1.960 (rounded to 3 decimal places). The value of the test statistic is 2.477 (rounded to 3 decimal places).
