![**ClariLinX Wireless Study: Service Plan Preferences**
ClariLinX Wireless, a start-up cell phone company, is evaluating whether to market specific phone service plans to distinct groups of customers. These groups are categorized into: single, working; married, working; and retired. A survey was conducted with 500 randomly selected potential customers where they were asked to identify the most important feature of a cell phone service plan. The features include: free nights and weekends, free long-distance and roaming, or free calls to customers within the same company.
**Study Variables:**
1. **Type of Potential Customer:**
- Single, working
- Married, working
- Retired
2. **Choice of Service Plan Feature:**
- Free calls to other customers
- Free nights and weekends
- Free long-distance and roaming
The contingency table summarizes the survey data, showing the observed frequency (f<sub>o</sub>), the expected cell frequency (f<sub>e</sub>), and the calculation for the test statistic using the formula:
\[
\frac{(f_o - f_e)^2}{f_e} \quad (\text{Observed cell frequency} - \text{Expected cell frequency})^2 / \text{Expected cell frequency}
\]
**Part 1: Contingency Table Analysis**
Complete the missing values in the table using the given data and round expected frequencies to two or more decimal places. Calculate the values for the test statistic and round off appropriately.

| **Total** | 99 | 150 | 251 | 500 |
Fill in the blank values by calculating expected frequencies and rounding them to two or more decimal places.
