A teacher is interested in whether the number of bullying incidents by active bullies varies by class. The following data are the number of bullying incidents that occurred for 5 individuals randomly selected from 4 separate classes. Test the null hypothesis at the .01 level of significance that bullying does not vary across class. In so doing, identify: (1) the research and null hypothesis, (2) the critical value needed to reject the null, (3) the decision that you made upon analyzing the data, and (4) the conclusion you have drawn based on the decision you have made. ### Educational Website: Table Explanation#### Data Table: Class StatisticsThe table below presents the statistical data for four different classes.| | Class 1 | Class 2 | Class 3 | Class 4 | TOTAL ||---------------|---------|---------|---------|---------|-------|| **Row 1** | 3 | 1 | 3 | 1 | 8 || **Row 2** | 1 | 1 | 5 | 2 | 9 || **Row 3** | 4 | 2 | 5 | 2 | 13 || **Row 4** | 3 | 4 | 5 | 1 | 13 || **Row 5** | 2 | 4 | 4 | 1 | 11 || **TOTAL** | 13 | 12 | 22 | 7 | 54 |#### Explanation- **Headers**: The top row of the table lists different columns, namely `Class 1`, `Class 2`, `Class 3`, `Class 4`, and `TOTAL`.- **Rows**: Each row contains numerical data corresponding to these classes, with the final column showing the sum total for each row.- **Final Row**: The last row in the table (`TOTAL`) provides the sum totals for each class. ##### Detailed Breakdown:- **Class Totals**: - `Class 1` has a total of 13 units. - `Class 2` has a total of 12 units. - `Class 3` has a total of 22 units. - `Class 4` has a total of 7 units. - **Row Totals**: - **Row 1**: 8 units. - **Row 2**: 9 units. - **Row 3**: 13 units. - **Row 4**: 13 units. - **Row 5**: 11 units. - **Final Sum (All Classes Combined)**: 54 units.This table clearly organizes and displays the data for easy comparison across different classes and categories.

Question

A teacher is interested in whether the number of bullying incidents by active bullies varies by class. The following data are the number of bullying incidents that occurred for 5 individuals randomly selected from 4 separate classes. Test the null hypothesis at the .01 level of significance that bullying does not vary across class. In so doing, identify: (1) the research and null hypothesis, (2) the critical value needed to reject the null, (3) the decision that you made upon analyzing the data, and (4) the conclusion you have drawn based on the decision you have made.

### Educational Website: Table Explanation

#### Data Table: Class Statistics

The table below presents the statistical data for four different classes.

| | Class 1 | Class 2 | Class 3 | Class 4 | TOTAL |
|---------------|---------|---------|---------|---------|-------|
| **Row 1** | 3 | 1 | 3 | 1 | 8 |
| **Row 2** | 1 | 1 | 5 | 2 | 9 |
| **Row 3** | 4 | 2 | 5 | 2 | 13 |
| **Row 4** | 3 | 4 | 5 | 1 | 13 |
| **Row 5** | 2 | 4 | 4 | 1 | 11 |
| **TOTAL** | 13 | 12 | 22 | 7 | 54 |

#### Explanation

- **Headers**: The top row of the table lists different columns, namely `Class 1`, `Class 2`, `Class 3`, `Class 4`, and `TOTAL`.
- **Rows**: Each row contains numerical data corresponding to these classes, with the final column showing the sum total for each row.
- **Final Row**: The last row in the table (`TOTAL`) provides the sum totals for each class.

##### Detailed Breakdown:
- **Class Totals**:
- `Class 1` has a total of 13 units.
- `Class 2` has a total of 12 units.
- `Class 3` has a total of 22 units.
- `Class 4` has a total of 7 units.

- **Row Totals**:
- **Row 1**: 8 units.
- **Row 2**: 9 units.
- **Row 3**: 13 units.
- **Row 4**: 13 units.
- **Row 5**: 11 units.
- **Final Sum (All Classes Combined)**: 54 units.

This table clearly organizes and displays the data for easy comparison across different classes and categories.
