Transcribed Image Text:The image contains a Chi-Square distribution table, which displays critical values used in statistical hypothesis testing. The table is organized by degrees of freedom (df) and different significance levels (alpha values).
### Explanation of the Table:
- **Columns**: The columns represent areas to the right of the critical value, corresponding to various alpha levels: 0.995, 0.99, 0.975, 0.95, 0.9, 0.1, 0.05, 0.025, 0.01, and 0.005.
- **Rows**: Each row represents a different degree of freedom (df), ranging from 1 to 100.
- **Critical Values**: The intersection of a specific degree of freedom and alpha level gives the critical value. These values are used to determine whether to reject the null hypothesis in a Chi-Square test.
### Additional Information:
- **Degrees of Freedom (df)**:
- \( n - 1 \): Confidence interval or test for standard deviations or variances.
- \( k - 1 \): Test of goodness of fit.
- \( (r - 1)(c - 1) \): Contingency table with \( r \) rows and \( c \) columns.
This table is a vital tool in statistical analysis, helping researchers and students determine the significance of their test results based on the Chi-Square distribution.
