Question
**Chi-Square Analysis Educational Exercise** **Objective:** Find the expected count and the contribution to the chi-square statistic for the (Group 3, No) cell in the two-way table below. **Two-Way Table:** | | Yes | No | Total | |----------|-----|----|-------| | Group 1 | 58 | 41 | 99 | | Group 2 | 136 | 63 | 199 | | Group 3 | 65 | 27 | 92 | | **Total**| 259 | 131| 390 | **Instructions:** 1. Round your answer for the expected count to one decimal place. 2. Round your answer for the contribution to the chi-square statistic to three decimal places. **Input Fields:** - Expected count = [Input Field] - Contribution to the chi-square statistic = [Input Field] **Resources:** - eTextbook and Media **Task:** Calculate the expected count for (Group 3, No) using the formula: \[ \text{Expected Count} = \frac{(\text{Row Total} \times \text{Column Total})}{\text{Grand Total}} \] Calculate the contribution to the chi-square statistic using the formula: \[ \chi^2 = \frac{(\text{Observed Count} - \text{Expected Count})^2}{\text{Expected Count}} \] Ensure accuracy by following the rounding instructions provided.
