Question
Do single-parent families tend to be more impoverished than families with two parents? In order to test if there is a relationship between family structure and family income level, a family researcher studied a sample of 35 one-parent and 65 two-parent families in a particular city to determine whether their total family income fell below the poverty level.

### Family Structure

| Total Family Income        | One Parent | Two Parents |
|----------------------------|------------|-------------|
| Below poverty level        | 24         | 20          |
| Not below poverty level    | 11         | 45          |

- **Which is the independent variable and which is the dependent variable?**
  
- **What is your null and research hypothesis?**

- **Which test should you use (Two Sample Independent t, ANOVA, Chi-square, or Correlation)?**

- **Calculate the test statistic.**

- **Please interpret whether you have statistically significant results when α = .05.**
  - a. State whether the null hypothesis is rejected. Please include the critical region in your answer.
  - b. Provide an overall sentence about the conclusion reached.

- **Please find the pattern of the relationship between total family income and poverty level. You should include all numbers to justify your answer.**
