Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

| 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.**](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F32f23a87-e079-4652-813d-ae6284c3f138%2Fcbf7177b-dc23-44b7-bdcc-aa05c54fa8c5%2Fglvi5xw_processed.png&w=3840&q=75)
