The leader of two postpartum women’s support groups is interested in the depression levels of the women in her groups. She administers the Center for Epidemiologic Studies Depression Scale (CES-D) screening test to the members of her groups. The CES-D is a 20-question self-test that measures depressive feelings and behaviors during the previous week. The mean depression level from the screening test for the 10 women in the first group is μ₁ = 16; the mean depression level for the 14 women in the second group is μ₂ = 10. Without calculating the weighted mean for the combined group, you know that the weighted mean is:
Your supervisor really appreciates you and, based on your hard work, is often doing her best to get you promoted, get raises, and so forth. You have some colleagues who are under-appreciated by their supervisors and have not received a raise or promotion in years. You believe that there is some relationship between how much a supervisor appears to be appreciative and the amount of money his/her subordinates make. To test this, you distributed a survey to all of the people in your organization who are in supervisory positions. You measure their appreciation for each individual works for them on a Likert-type scale of 1-5. You also have corresponding data for supervisors' employees' salaries. What test would you use to discover if there is something to the notion that you have? a. Regression b. Matched pairs t-test C. None of these Inependent samples t-test e. Correlation O f. Chi-square g. ANOVA
Polyunsaturated fatty acids in the diet favorably affect several risk factors for cardiovascular disease. The principal dietary polyunsaturated fat is linoleic acid. Suppose we randomly selected twelve adults for our study. We took their blood pressure measurements (systolic blood pressure) at the start and recorded them for each adult. Then we placed required these adults to consume 23g/day of safflower oil which is high in linoleic acid for four weeks. At the end of the four weeks, we took another systolic blood pressure(SBP) measurement. The paired data is provided below: Subject 1 2 3 4 5 6 7 8 9 10 11 12 Baseline SBP 119.67 100.00 123.56 109.89 96.22 133.33 115.78 126.39 122.78 117.44 111.33 92.39 1-month SBP 117.33 98.78 123.83 107.67 95.67 128.89 113.22 121.56 126.33 110.39 107.00 93.06 Use the appropriate nonparametric test at alpha level of 0.05, to test whether the diet heavy in linoleic acid increases systolic blood pressure (SBP).
A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of eight ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain.BIG Corporation would like to estimate the mean amount of coffee, μ, dispensed per cup by this machine. BIG will choose a random sample of cup amounts dispensed by this machine and use this sample to estimate μ. Assuming that the standard deviation of cup amounts dispensed by this machine is 0.42 ounces, what is the minimum sample size needed in order for BIG to be 90% confident that its estimate is within 0.07 ounces of μ? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).
5 to 10 grams or more of soluble fiber a day decreases your LDL cholesterol according to Mayo Clinic. A cereal manufacturer 'Healthy Goals' claims that their high fiber cereals help reduce the LDL numbers among 76% people who eat 'Healthy Goals' cereals. In a random sample of 65 people who eat cereals made by 'Healthy Goals' 44 reported their LDL cholesterol numbers being lowered. Based on this sample is the claim made by the company that 76% lower their LDL really true?" Do necessary calculation and answer the question. Do not simply put down yes/no answers.

Should there be a significant difference with this study, what post-hoc test shall be used? Dr. Hess has done work that suggests that emotional arousal affects pupil size. To ascertain if the type of arousal makes a difference, you decided to measure pupil size under three different arousal conditions (Neutral, Pleasant, Aversive). Each participant will look at all the different pictures that differ according to the condition. The pupil size after viewing each photograph is measured in millimeters. * t-Test paired two sample for means O t-Test assuming equal variances O t-Test assuming unequal variances
Determine whether the results appear to have statistical significance, and also determine whether theresults appear to have practical significance: Bias in Jury Selection In the case of Casteneda v. Partida, it was found that during a period of 11 years in Hidalgo County, Texas, 870 people were selected for grand jury duty, and 39% of them were Americans of Mexican ancestry. Among the people eligible for grand jury duty, 79.1% were Americans of Mexican ancestry.Please explain it step by step, thank you.
A study was conducted to examine how anxiety (measured on a metric scale) varies for people from different age groups (<18 years, 19 - 29 years, 30 - 39 years, 40+ years). It was hypothesised that people <18 years old would have the least anxiety of the four age groups. It was also hypothesised that people 40+ years old would have more anxiety than people 19-29 years old. Which of the following would be an appropriate statistical test to conduct, which addresses these hypotheses? Group of answer choices: Factorial ANOVA Multiple Regression Mixed ANOVA Single factor ANOVA Within Subjects ANOVA

The accounts receivable department at Rick Wing Manufacturing has been having difficulty getting customers to pay the full amount of their bills. Many customers complain that the bills are not correct and do not reflect the materials that arrived at their receiving docks. The department has decided to implement SPC in its billing process. To set up control charts, 10 samples of 100 bills each were taken over a month's time and the items on the bills checked against the bill of lading sent by the company's shipping department to determine the number of bills that were not correct. The results were: Sample No. No. of Incorrect Bills a) The value of mean fraction defective (p): = 1 2 2 0 3 13 4 2 5 0 6 6 7 7 (enter your response as a fraction between 0 and 1, rounded to four decimal places). 8 1 9 3 10 3
