5.3.18 From Exercise 5.2.19, recall the results from a 2013 Gallup poll that asked randomly selected U.S. adults whether they wanted to stay at their current body weight or change. Of the 562 men surveyed, 242 wanted to stay at their current weight, whereas of the 477 women surveyed, 172 wanted to stay at their current weight. Define (in words) the parameters of interest of this study. Also, assign symbols to the parameters. State the appropriate null and alternative hypotheses in words. State the appropriate null and alternative hypotheses in symbols. Explain why it is valid to use the theory-based approach to test the hypotheses stated above. Use an appropriate applet to find a theory-based p-value to test the above hypotheses. Report the standardized statistic as well as the p-value. Use an appropriate applet to find a theory-based 95% confidence interval and interpret the resulting interval in the context of the study. Based on your findings, state a complete conclusion about the study. Be sure to address significance, estimation (confidence interval), causation, and generalization.
