5. Using the data file nes.dta, produce a crosstab table with chi- square statistic to examine the relationship between attitudes toward gun control and region of residence. You may use the existing variable gun_control2 as the dependent variable. For the independent variable, create a dummy variable that has the value of 1 for South, and 0 otherwise. (You may have created this dummy variable in an earlier assignment and saved it. If not, use the tabulate command with the gen option to ask Stata to create a dummy variable for each category of region). Once you have produced the crosstab table, use it to answer the following questions. a) What percentage of southerners favors making it more difficult to buy a gun? What percentage of non-southerners favors making it more difficult to buy a gun? b) Is there a statistically significant relationship between residing in the South and attitudes toward gun laws? Explain how you know. c) Create another crosstab table that adds a control for gun_own, a third variable that one might expect to be related to attitudes on gun control. Include a chi-square test with your crosstab. Is there a statistically significant relationship between region of residence and attitudes toward gun laws across all levels of the control variable? How do you know? Interpret the output, explaining what the results tell you about the relationship between the three variables
