In a recent Harris Poll, a random sample of adult Americans (18 years and older) was asked, "Given a choice of the following, which one would you most want to be?" Results of the survey, by gender, are given in the contingency table. $$\begin{array}{lcccccc} & \text { Richer } & \text { Thinner } & \text { Smarter } & \text { Younger } & \begin{array}{l}\text { None of } \\\text { these }\end{array} & \text { Total } \\\hline \text { Male } & 520 & 158 & 159 & 181 & 102 & 1120 \\\hline \text { Female } & 425 & 300 & 144 & 81 & 92 & 1042 \\\hline \text { Total } & 945 & 458 & 303 & 262 & 194 & 2162\end{array}$$ (a) How many adult Americans were surveyed? How many males were surveyed? (b) Construct a relative frequency marginal distribution. (c) What proportion of adult Americans want to be richer? (d) Construct a conditional distribution of desired trait by gender. That is, construct a conditional distribution treating gender as the explanatory variable. (e) Draw a bar graph of the conditional distribution found in part (d). (f) Write a couple sentences explaining any relation between desired trait and gender.
