A survey includes the question, "Taken all together, would you say that you are very happy, pretty happy, or not too happy?" The table uses the survey to cross-tabulate happiness with family income, measured as the response to the question, "Compared with families in general, would you say that your family income is below average, average, or above average?" The concern is whether happiness varies depending on income level. a. Identify the response variable and the explanatory variable. O Happiness is the explanatory variable and income is the response variable. Income is the explanatory variable and happiness is the response variable. b. Construct the conditional proportions on happiness at each level of income. Interpret and summarize the association between these variables.
