### Educational Content**Topic: Analysis of Cross-Tabulation and Chi-Square Test**#### a. Cross-Tabulation Analysis- **Task**: Perform a percentage-based cross-tabulation.- **Objective**: Determine if there is a relationship between gender and opinions on restoring voting rights for felons in prison.- **Process**: Evaluate the data distribution to identify any notable patterns or associations between the two variables.#### b. Chi-Square Test Result- **Chi-Square Value**: 0.2512- **Significance Level (Alpha)**: 0.05- **Interpretation**: - The chi-square test assesses whether there is a statistically significant association between gender and views on the restoration of voting rights for felons. - **Conclusion**: With a chi-square value of 0.2512 at an alpha of 0.05, determine if the result is statistically significant. If it is below the critical value, it suggests no significant relationship; if above, a potential association exists. **Cross-Tabulation of Views on Restoring Voting Rights for Felons in Prison by Gender**This table presents a cross-tabulation of views on restoring the voting rights of felons in prison, based on a March 2018 randomly selected sample of U.S. citizens aged 18 years and older.

On the following pages you are presented with five problems. Your job is to examine the output and discuss whether there is a statistically significant relationship between the two variables, the pattern or direction of the relationship if the relationship is significant, and the strength of the relationship if the relationship is significant. AS you discuss the strength of the relationship, you will rely on an appropriate measure of association from those that have been given. For that determination, you will need to appropriately determine the level of measurement of each of the variables being examined. Please use the Measures of Association Chart I provided to help you with your determination. You may write your responses on a separate document or next to the problems on this one.

Political parties want to know what groups of people support them. The General Social Survey (GSS) asked its 2014 sample, "Generally speaking, do you usually think of yourself as a Republican, Democrat, Independent, or what?" The GSS is essentially an SRS of American adults. The large two‑way table provided breaks down the responses by the highest degree the subject held. None High School Jr. College Bachelor Graduate Strong Democrat 53 198 23 81 64 Not strong Democrat 52 204 31 70 49 Independent, near Democrat 40 163 26 66 42 Independent 118 251 36 67 30 Independent, near Republican 24 136 19 45 2525 Not strong Republican 19 142 30 71 30 Strong Republican 18 131 15 53 28 Other party 5 31 3 15 8 Use the four‑step process and the full table of counts to analyze the differences in political party support among levels of education. The sample is so large that the differences are bound to be highly significant, but provide the chi‑square statistic and its P‑value…
