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.
