A researcher is interested in the idea of a Protestant work ethic. She conducts a random survey on weekly hours worked by people in employment. The 3,453 Protestants in the survey work a mean of 39.360 hours per week, with a standard deviation of 13-182 hours, while the 6,044 Catholics work a mean of 42.206 hours per week with a standard deviation of 13.690 hours. a. Assuming the population variances are the same is there any evidence that Protestants work more hours than Catholics? b. Test whether the assumption of equal population variances is valid and, if necessary, redo part a assuming the population variances are different. c. Does this tell us whether the Protestant work ethic exists? Be sure to explain why or why not.
In the year 2033, katy perry is a leading traveling nurse. Katy is interested in reducing the mean recovery time for patients after experiencing a serious injury (assume recovery times are normally distributed). Suppose the mean recovery time is presently 8.6 months. Katy takes a random sample of 46 patients that have experienced serious injury to participate in a new treatment program and finds the sample mean is 8.1 months and a sample standard deviation of 1.2 months. Using a = 0.05, answer the following questions. d) Using the appropriate level of confidence, what is the confidence interval? e) What is the interpretation (not your conclusions) of the confidence interval (in the context of the problem) you obtained in part c? f) What is the p value?
Low-fat or low-carb? Are low-fat diets or low-carb diets more effective for weight loss? A sample of 77 subjects went on a low-carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 4.4 kilograms with a sample standard deviation of 7.3 kilograms. A second sample of 81 subjects went on a low-fat diet. Their sample mean weight loss was 2.7 kilograms with a standard deviation of 5.8 kilograms

In a study of birth order and intelligence, IQ tests were given to 18 - and 19 -year-old men to estimate the size of the difference, if any, between the mean IQs of firstborn sons and secondborn sons. The following data for 10 firstborn sons and 10 secondborn sons are consistent with the means and standard deviations reported in the article. It is reasonable to assume that the samples come from populations that are approximately normal. Can you conclude that the mean IQ of firstborn sons differs from the mean IQ of secondborn sons? Let μ1 denote the mean IQ of firstborn sons and μ2 denote the mean IQ of secondborn sons. Use the =α0.05 level and the P -value method with the TI-84 Plus calculator. reject or not is there evidence or not Firstborn 101 84 122 84 88 97 130 109 83 93 Secondborn 115 125 84 112 113 113 129 83 97 126
