1. In the 2008 General Social Survey, incomes of marriedrespondents were classified as above average, average, and belowaverage. Respondents also answered a question about maritalhappiness as not happy, pretty happy, or very happy. The resultsare below:

	Marital Happiness
Income	Not Happy	Pretty Happy	Very Happy	Totals
Above Average	123	105	7	235
Average	291	151	17	459
Below Average	172	83	6	261
Totals	586	339	30	955

Conduct an appropriate test todetermine whether or not there is a statistically significantassociation between marital happiness and income at the 5%significance level.

1. Which is the independent variable and which is the dependentvariable?
2. For individuals with average income, what percentage ofindividuals report their marital happiness as “pretty happy?”
3. Are the basic assumptions of the hypothesis testsatisfied?
4. What are the null and alternative hypotheses?
5. Based on the significance level at which you are testing, whatis (are) the critical value(s) for the test?
6. Calculate the appropriate test statistic, showing all yourwork. You should explicitly display (1) expected values for eachcell and (2) the test statistic contribution of each cell inaddition to calculating the overall test statistic.
7. Calculate the corresponding p-value from the appropriate tableor online calculator.
8. What conclusions can you draw from the hypothesis test? Be sureto comment on evidence from both the test statistic andp-value.
