16. Research subjects were followed from adolescence to adulthood, and all the people in Obese Dating Cohabiting Married 76 101 153 the sample were categorized in terms of whether Not Obese they were obese and whether they 360 321 274 were dating, cohabiting, or married. Test the hypothesis that relationship status and obesity are related, using a significance level of 0.05. Can we conclude from these data that living with someone is making some people obese and that marrying is making people even more obese? Can we conclude that obesity affects relationship status? Explain. Choose the correct null hypothesis (Ho) and alternative hypothesis (HA). A. Ho: Obesity and relationship status have equal proportions. HA: Obesity and relationship status have non-equal proportions. 'B. Ho: Obesity and relationship status are independent. HA: Obesity and relationship status are related. C. Ho: Obesity and relationship status are related. HA: Obesity and relationship status are independent. D. Ho: Obesity and relationship status have a p-value of 0.05. HA: Obesity and relationship status do not have a p-value of 0.05. Calculate the chi-square test statistic. (Round to two decimal places as needed.) Determine the p-value. (Round to three decimal places as needed.) Reject or do not reject the null hypothesis, and state what that means. A. Reject Ho and conclude that obesity and relationship status are related. B. Fail to reject Ho and conclude that obesity and relationship status are not related. C. Reject Ho and conclude that obesity and relationship status are not related. D. Fail to reject Ho and conclude that obesity and relationship status are related. Can we conclude from these data that living with someone is making some people obese and that marrying is making people even more obese? Can we conclude that obesity affects relationship status? Explain why or why not. A. Yes. Since cohabiting and married people have a higher rate of obesity, it is clear that being obese increases the chances of getting married. B. No. Obesity rates actually decrease in cohabitating and married people. C. Yes. Since the obesity rate is higher in cohabiting and married people, it can be concluded that marriage can cause obesity. D. No. Although a relationship is evident, this is an observational study and cannot be used to prove causality.
