Researchers studying the relationship between anxiety and health have a health status assessment and an anxiety assessment. They measure both for the middle-aged adult employees of a certain company and obtain the following results. Average anxiety score = 60 points Average health score = 70 points 1. Interpret the correlation coefficient. 2. For a middle-aged adult scoring 55 on the anxiety scale, the regression line predicts their health score to be about give or take SD = 4 points SD = 8 points, r=-0.40 3. For a middle-aged adult scoring 65 on the anxiety scale, the regression line predicts their health score to be about give or take 4. For someone chosen at random from the entire group of middle-aged adults, we expect their health score to be give or take 5. For someone scoring at the 25th percentile on the anxiety score, predict their percentile rank for the health score. 6. Find the regression line for the regression of health score on anxiety. 7. Suppose that the researchers obtain a contentment score using the anxiety score and computing the following: Contentment score = 100-(0.5) (anxiety score). For the researchers' middle-aged adult at this company, find the following: a) The contentment score average. b) The contentment score SD. c) The correlation between the contentment score and the health score. d) The correlation between the anxiety and contentment score.
