To construct a frequency distribution from Kevin's data, we follow the steps given in the question: use 4 classes, a class width of 2 hours, and a lower limit of 3 for the first class.

### Step 1: Organize the Data
The data set is:
- 56, 54, 55, 98, 53, 76, 67, 56, 75, 67, 56, 68, 67, 84

### Step 2: Determine Class Limits
- Start with the lower limit of 3 and use a class width of 2.
- Class limits will be determined as follows:

| **Class** | **Lower Limit** | **Upper Limit** | **Class Width** |
|:---------:|:---------------:|:---------------:|:---------------:|
| 1         | 3               | 4               | 2               |
| 2         | 5               | 6               | 2               |
| 3         | 7               | 8               | 2               |
| 4         | 9               | 10              | 2               |

### Step 3: Frequency Distribution Table
| **Class Interval** | **Frequency** |
|:------------------:|:-------------:|
| 3 - 4              |       0       |
| 5 - 6              |       0       |
| 7 - 8              |       0       |
| 9 - 10             |

Kevin asked some of his friends how many hours they had worked during the previous week at their after-school jobs. The results are shown below: 56, 54, 55, 98, 53, 76, 67, 56, 75, 67, 56, 68, 67, 84. Construct a frequency distribution. Use 4 classes, a class width of 2 hours, and a lower limit of 3 for class 1.

Learn how to construct a frequency distribution for the hours worked by Kevin's friends in their after-school jobs. This solution explains data organization, using 4 classes, a class width of 2 hours, and a lower limit of 3. Suitable for students in Grades 9-12.
