4. Straight As now, healthy later A study by Pamela Herd of the University of Wisconsin-Madison found a link between high-school grades and health. Analyzing data from the Wisconsin Longitudinal Study, which has tracked the lives of thousands of Wisconsin high-school graduates from the class of 1957, Herd found that students with higher grade-point averages were more likely to say they were in excellent or very good health in their early 60s. Does this mean people will live healthier lives if they increase their GPA? Explain.47
Katy Deen, who has just been appointed general manager of the Oca's Wellness and Resort Place, has been given instructions to "get things under control". Upon reviewing the business' income statement, Ms. Deen has concluded that the major problem lies in the variable cost of external services for cleaning and maintenance. She has been provided with the following standard cost in dollars per hour of a certain week of three different maintenance groups for cleaning the swimming pool. Level of significance is 0.01. 1.What is the TOTAL Sum of Squares of the problem? Round off your final answer to TWO decimal places. 2. What is the value of the Mean Sum of Squares Between? Round off your final answer to TWO decimal places. 3. What is the value of the Mean Sum of Squares Within? Round off your final answer to TWO decimal places. 4.

The report “Undergraduate Students and Credit Cards in 2004: An Analysis of Usage Rates and Trends” (Nellie Mae, May 2005) estimated that 21% of undergraduates with credit cards pay them off each month and that the average outstanding balance on undergraduates’ credit cards is $2169. These estimates were based on an online survey that was sent to 1260 students. Responses were received from 132 of these students. Is it reasonable to generalize the reported estimates to the population of all undergraduate students? Address two possible sources of bias, and name the bias in your answer.
4. Along with interest rates, life expectancy is a component in pricing financial annuities. Suppose that you know that last year average life expectancy was 77 years for your annuity holders. Now you want to know if your clients this year have a longer life expectancy, on average, so you randomly sample n=20 of your recently deceased annuity holders to see actual age at death. Using a 5% level of significance, test whether or not the new data shows evidence of your annuity holders now live longer than 77 years, on average. The data below are the sample data (in years of life): (78,75,83,81,81,77,78,79,79,81,76,79,77,76,79,81,73,74,78,79) a) Does this sample indicate that life expectancy has increased? Test an appropriate hypothesis and state your conclusion (use a 5% level of significance). Be sure to check the necessary assumptions and conditions before conducting your test. b) Construct A 90% confidence interval for the true average age of death for the population of your annuity…

D Country Financial, a financial services company, uses surveys of adults age 18 and older to determine whether personal financial fitness changing over time. A recent sample of 1000 adults showed 410 indicating that their financial security was more than fair. Just a year prior, a sample of 900 adults showed 315 indicating that their financial security was more than fair. a. State the hypotheses that can be used to test for a significant difference between the population proportions for the two years. Ho : P1 – p2- Select your answer - Ha : Pi - P2 - Select your answer - b. Conduct the hypothesis test and compute the p-value. Round your answer to four decimal places. p-value = %3D At a = 0.05 level of significance, what is your conclusion? I. Reject Ho. There is not sufficient evidence to conclude that the population proportions are not equal. The data do not suggest that there has been a change in the population proportion saying that their financial security is more than fair. II.…

Estimating income tax based on dividends is also not straightforward, due in part to Australia’s franking credit scheme. Mike is looking to simplify total annual tax projections for a share portfolio based simply on the share portfolio's current value. To do this, he wishes to determine if there is any statistically significant linear relationship between the two. Mike has randomly sampled 30 individuals with share portfolios over AUD$100,000 and mapped the assessed value of the portfolio (in AUD $1000) to the total taxes paid on that amount (in AUD$1). Mike's data is in the table below. Assessed Value Taxes 426.1 5014 368.8 3698 309.8 3691 373.9 5189 445.7 4455 505.1 5189 342.3 3416 343.6 3931 432.3 4393 329.2 3267 291.2 2871 399.3 4013 392.7 4728 482.2 4885 480.6 4888 390.8 3917 371.6 3738 311.9 3098 343.7 3633 304.7 3538 274.6 3427 457.1 4633 231.5 4009 450.5 4565 510.1 5946 308.4 3045 348.8 3504 410.4 3375…

Triglycerides are blood constituents that are thought to play a role in coronary artery disease. An experiment was conducted to see if regular exercise could reduce triglyceride levels. Researchers measured the concentration of triglycerides in the blood serum of seven male volunteers before and after participation in a 10-week exercise program. The results are shown below. Note the variation in levels from one person to the next, both before and after. But an overall pattern of reduction after exercise is clear. An obvious question to ask is: Does exercise reduce triglyceride levels? (Hint: This is the same as asking "Are the mean triglyceride levels in the blood serum of males higher before participation in a 10 week exercise program?") Conduct a significance test at the 0.05 level of significance to answer the proposed research question.
