**Title: Creating a Stem-and-Leaf Display**

**Instructions:**

Here are the final scores for the last 16 games played by the local basketball team. Construct a stem-and-leaf display for the given data.

**Scores:**
- 45, 54, 53, 65
- 67, 75, 57, 59
- 87, 86, 79, 74
- 67, 75, 87, 65

**Stem-and-Leaf Display Options:**

**A.**
```
4 | 45
5 | 53 54 57 59
6 | 65 65 67 67
7 | 74 75 75 79
8 | 86 86 87
```

**B.**
```
4 | 5
5 | 3 4 7 9
6 | 5 7
7 | 4 5 9
8 | 6 7
```

**C.**
```
4 | 5
5 | 3 4 7 9
6 | 5 5 7 
7 | 4 5 5 9
8 | 6 7 7
```

**D.**
```
4 | 45
5 | 53 54 57 59
6 | 65 67
7 | 74 75 79
8 | 86 87
```

**Explanation:**

A stem-and-leaf display is a way to visually organize data. Each number's stem (such as the tens digit) is listed in a column, and every corresponding leaf (such as the units digit) is placed in a row to the right of the stem. This method keeps the data organized while also showing its distribution.

Use this guidance to identify the correct stem-and-leaf display for the provided scores.

A random sample of 30 college students is selected. Each student is asked how much time he or she spent on homework during the previous week. The following times (in hours) are obtained:

21, 15, 24, 23, 25, 19, 24, 22, 15, 15, 25, 16, 24, 17, 23, 18, 22, 19, 24, 24, 19, 21, 15, 17, 18, 22, 15, 18, 16, 17

Construct a frequency distribution for the data.

Type the frequency for each data value.

| Hours Studied | Frequency |
|---------------|-----------|
|      15       |           |

(Note: The table is partially filled and ready for completion. The task is to determine how often each number occurs in the data set and input those frequencies.)
