- If a researcher is interested in cause-and-effect relationships, which nonexperimental design should she use? A. The second simple case of nonexperimental research B. Neither the first nor second case of nonexperimental research can provide evidence of causality C. Either the first or second case of nonexperimental research would be sufficient for this study D. The first simple case of nonexperimental researchInvestment advisors agree that near-retirees, defined as people aged 55 to 65, should have balanced portfolios. Most advisors suggest that the near-retirees have no more than 50% of their investments in stocks. However, during the huge decline in the stock market in 2008, 15% of near-retirees had 90% or more of their investments in stocks (P. Regnier, “What I Learned from the Crash,” Money, May 2009, p. 114). Suppose you have a random sample of 12 people who would have been labeled as near-retirees in 2008. What is the probability that during 2008: two or more had 90% or more of their investment in stocks?Define multiperiod forecasting. Which Method Should we Use?

Suppose six individuals, within your criteria, are randomly selected. Show or explain your thinking for each problem. (Note: This is a binomial probability from Section 5.2, they either have insurance or they do not.) A. Let having insurance be a success. State the values of your p, q, and n for your chosen condition. Explain your thinking. (For my example, if 22% do not have insurance, then that is my q (failure) value, my p=0.78, q=0.22, n-6 (6 individuals are randomly selected in this problem). B.
