Answer 1

To determine the frequencies of the given class intervals, we will count how many students' textbook expenses fall within each of the specified dollar ranges.

Here is the list of amounts:
22, 43, 29, 55, 28, 36, 26, 51, 63, 62, 23, 48, 62, 59, 36, 42, 28, 53, 66, 59

Let's categorize these amounts into the class intervals:

- 20-29
- 30-39
- 40-49
- 50-59
- 60-69

Now we count the number of amounts in each interval:

1. **Interval 20-29:**
- 22
- 29
- 28
- 26
- 23
- 28
Total: 6

2. **Interval 30-39:**
- 36
- 36
Total: 2

3. **Interval 40-49:**
- 43
- 48
- 42
Total: 3

4. **Interval 50-59:**
- 55
- 51
- 53
- 59
- 59
Total: 5

5. **Interval 60-69:**
- 63
- 62
- 62
- 66
Total: 4

So, the frequencies filled in the table are:

**Interval (in Dollars)**|**Frequency**
-------------------------|---------
20-29 |6
30-39 |2
40-49 |3
50-59 |5
60-69 |4

These are the frequencies for the given class intervals based on the data provided.
