1. **State the problem:** We are given a data set: 3, 7, 7, 3, 2, 7, 7, 3, 2, 4, 6, 7, 6, 2, 2. We need to complete the frequency table for the intervals 0-1, 2-3, 4-5, and 6-7.
2. **Recall the frequency table concept:** A frequency table counts how many data points fall into each interval.
3. **Count the data points in each interval:**
- Interval 0-1: Numbers between 0 and 1 inclusive. None in the data set.
- Interval 2-3: Numbers 2 or 3.
- Interval 4-5: Numbers 4 or 5.
- Interval 6-7: Numbers 6 or 7.
4. **Count each interval:**
- For 0-1: No numbers, so frequency = 0.
- For 2-3: Count 2's and 3's.
- 2 appears 4 times.
- 3 appears 3 times.
- Total frequency = 4 + 3 = 7.
- For 4-5: Count 4's and 5's.
- 4 appears 1 time.
- 5 appears 0 times.
- Total frequency = 1 + 0 = 1.
- For 6-7: Count 6's and 7's.
- 6 appears 2 times.
- 7 appears 4 times.
- Total frequency = 2 + 4 = 6.
5. **Fill in the tally marks:**
- 0-1: No tally marks.
- 2-3: Seven tally marks (|||| |||).
- 4-5: One tally mark (|).
- 6-7: Six tally marks (|||| ||).
6. **Final frequency table:**
| Interval | Tally | Frequency |
|----------|-----------|-----------|
| 0 - 1 | | 0 |
| 2 - 3 | |||| ||| | 7 |
| 4 - 5 | | | 1 |
| 6 - 7 | |||| || | 6 |
This completes the frequency table for the given data set.
