Good Morning, Based on the scenario and the data output, I would like to confirm that we would reject the null hypothesis and if so does that indicate non-signifigant or significant when relating to a CHI-Square statistical test? Thank you Scenario: In the recent COVID-19 pandemic, a local precinct observed that of the 75 people who voted, 25 identified as republican, 30 were democrat, and 20 were “other”. Is this similar to pre-pandemic voting based on political party affiliations? At that same precinct, pre-pandemic voting based on political party affiliation was: 35% republican, 44% democrats, and 21% “other”. Enter in the 75 data points and expected values into SPSS to conduct the appropriate statistical test. **Affiliation Table**| Affiliation | Observed N | Expected N | Residual ||---------------|------------|------------|----------|| Republican | 25 | 26.3 | -1.3 || Democrat | 30 | 33.0 | -3.0 || Other | 20 | 15.8 | 4.3 || **Total** | **75** | | |**Test Statistics**- **Chi-Square**: 1.479- **Degrees of Freedom (df)**: 2- **Asymptotic Significance (Asymp. Sig.)**: 0.477**Notes**:- 0 cells (0.0%) have expected frequencies less than 5. - The minimum expected cell frequency is 15.8.This table and test statistics are part of a chi-square test evaluating the affiliation of a sample. The categories include Republican, Democrat, and Other, showing observed numbers versus expected numbers. Residuals indicate the difference between observed and expected counts. The chi-square statistic measures the overall difference, with degrees of freedom and significance level providing insight into the statistical relevance of the affiliations.

The p-value is 0.477. If we see at 0.05 level of significance then if p-value is less than 0.05 then we reject null hypothesis that means the result is statistically significant. But here p-value is greater than 0.05 level of significance so we do not reject null hypothesis hence it is not statistically significant.

Good Morning,

Based on the scenario and the data output, I would like to confirm that we would reject the null hypothesis and if so does that indicate non-signifigant or significant when relating to a CHI-Square statistical test? Thank you
