The University of Michigan Health and Retirement Study (HRS) surveys more than 22,000 Americans over the age of 50
every two years. A subsample of the HRS participated in an Internet-based survey that collected information on a number of
topical areas, including health (physical and mental health behaviors), psychosocial items, economics (income, assets,
expectations, and consumption), and retirement. Two of the questions asked were: "Would you say your health is excellent,
very good, good, fair, or poor?" and “Do you smoke cigarettes now?" Here is the two-way table that summarizes the answers

As part of a long-term study of individuals 65 years of age or older, sociologists and physicians at the Wentworth Medical Center in upstate New York investigated the relationship between geographic location and depression. A sample of 60 individuals, all in reasonably good health, was selected; 20 individuals were residents of Florida, 20 were residents of New York, and 20 were residents of North Carolina. Each of the individuals sampled was given a standardized test to measure depression. Higher test scores indicate higher levels of depression.
A second part of the study considered the relationship between geographic location and depression for individuals 65 years of age or older who had a chronic health condition such as arthritis, hypertension, and/or heart ailment. A sample of 60 individuals with such conditions was identified. Again, 20 were residents of Florida, 20 were residents of New York, and 20 were residents of North Carolina.

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumer complaints ("Consumer fraud and," 2008). Do these data provide enough evidence to show that Arkansas had a higher proportion of identity theft than 23%? Test at the 5% level.

- 1. A researcher is interested in the effects of nature and nurture on altruism. Participants were adopted children. To study nature, birth parents were categorized as being high or low in altruism. To study nature, adoptive parents were categorized as being high, medium or low in altruism. The adopted children were given an altruism questionnaire, where higher scores reflect more altruism. Does Nature and/or Nurture contribute to children's altruistic behavior? Complete the conclusion statement below. Assume a = .05 and Tukey HSD = 9.6. Birth Parents (A) HIGH LOW High M = 80 M = 60 Adoptive Parents (B) Medium M = 70 M = 50 Low M = 60 M = 40 The factorial ANOVA revealed significant main effects of Birth Parents [F(1, 30) = 5.28, p .05].arrow_forwardIn a study examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that a man's sense of humor had significant effect on how he was perceieved by woman. In the study, female college students were given brief descriptions of a po tential romantic partner and then rated the attractiveness of the male on a scale from 1 (low) to 7 (high). The fictitious male was described positively as being single , ambitious, and having good job prospects. In one dition, the description also said that he had a great sense of humor. The results showed that the description was rated significantly higher when "a sense of humor" was included. To further examine this effect, a researcher selected a sample of n = 16colle college males and asked them to read a brief description of a female and then rate the attractiveness of the woman in the description . The description had been used in previous research but was modified by adding a statement describing a good sense of humor…arrow_forwardSeattle Grace Medical Center.
