A paint company has large outlet stores in two cities. Ten samples of the weekly sales (in tons) for the two cities areas follows.S1 = 4.3,S2City A: n = 10,X10 = 148.5,%3DCity B: n = 10,Y 10 = 144.2,= 3.8.Obtain a 98 percent confidence interval for the ratio of the two population standard deviations. Justify any assumptionthat you may be making.The following `answers" have been proposed.(a) The confidence interval foris [0.296, 5.54). No further assumptions are needed.(b) The confidence interval foris [0.296, 5.54]. We assumed that the weekly sales are normally distributed.(c) The confidence interval foris [0.24, 6.85]. We assumed that the weekly sales are normally distributed.(d) The confidence interval foris [0.24, 6.85]. We assumed that the weekly sales are normally distributed and the meansof the two populations are equal.(e) None of the above.The correct answer is(a)(b)(c)(d)(e)N/A(Select One)

A researcher predicts that showing a certain film will change people's attitudes toward alcohol. The researchers then randomly select 36 people, show them the film, and give them an attitude questionnaire. The mean score on the attitude questionnaire for this sample of people is 70. In the general population, the average score for people on this test is 75, with a standard deviation of 12 (assume the alpha level = .05) 1. Identify the independent variable. 2. identify the dependent variable. 3. in a sentence, state the null hypothesis. 4. Using symbols, state the null hypothesis. 4. Using symbols, state the alternative hypothesis.
A group of students in experimental lab are wanting to see if the average psychology major at a university has the same level of psychological knowledge as the general population. They assess 31 psychology majors using an overall psychology assessment and calculate a mean score of 20.91 and a standard deviation of 1.63. They know the general population has a mean score on this test of 18.32. The students think that psychology majors will know more about psychology than the general population. Name the: 1) independent variable 2) scaling for independent variable 3) dependant variable 4) scaling for dependent variable Answer the following questions: 5) can random Selection be used, explain 6) can random assignment be used, explain 7) based on what you know what statistical test should the students use to examine their hypothesis? 8) why is that test most appropriate? 9) what are the assumptions of this test? 10) what is the Null and alternative hypothesis? 11) what is/are the…

You want to see if the average grade for nontraditional age students is less than the average grade for traditional age students. You believe both populations are normally distributed, but you do not know the standard deviations for either. You obtain the following two samples of data.

Two estimates are available for the same population parameter. Estimate one has a standard deviation of 8.5 and estimate two has a standard deviation of 8.7. Estimate two is unbiased, whereas estimate one is biased. Which estimate would you choose and why?
Researchers want to compare the relative effectiveness of two popular diets. They randomly assign each of 400 volunteers to one of two Groups: A & B. There are 200 volunteers in each group. Group A spends 6 months on Diet A. Group B spends 6 months on Diet B. At the beginning of the study, the difference in average weight between the two groups was negligible. After the study, the Group A had lost on average 7.8 pounds with a standard deviation of 13.4 pounds, while the Group B had lost on average 5.3 pounds with a standard deviation of 14.8 pounds. Determine the z-score/test statistic for a two-tailed test with significance level α = 0.05 , accurate to 2 decimal places.
