Question: Suppose a researcher is interested in testing whether the distribution of income classifications (low, middle, high) are the same for males and for females in a particular state. A random sample is drawn from that state, consisting of 500 males and 450 females and the income classification of each individual is collected. The data are summarized below in the crosstabs table. Using the sample data, provide evidence for whether the income classification distribution is the same for males and females in the state. As part of your answer please provide the following:

1. the null and alternative hypothesis of the statistical test you choose

2. the test statistic for testing the null hypothesis

3. whether the null hypothesis is rejected (use a=.05)

4. a substantive summary of what the researcher found about the distribution of income classifications for males and females in the state.
