Answer :

To solve this question, we need to count the occurrences of numbers within two specified intervals from the given data lists.

Here's a step-by-step explanation:

1. Separate the data into individual lists:

- List 1: [64, 14, 17, 48, 58, 60, 43.44, 15, 32]
- List 2: [47, 21, 23, 37, 51, 26, 10, 36, 22, 24]
- List 3: [43, 45, 29, 33, 48, 38, 19, 38, 36, 30]
- List 4: [31, 72, 57, 41, 41, 44, 54, 24, 26, 41]

2. Combine all data into a single list:

- Combined data: [64, 14, 17, 48, 58, 60, 43.44, 15, 32, 47, 21, 23, 37, 51, 26, 10, 36, 22, 24, 43, 45, 29, 33, 48, 38, 19, 38, 36, 30, 31, 72, 57, 41, 41, 44, 54, 24, 26, 41]

3. Count the occurrences in each interval:

Interval 10-19:
- Numbers in this interval: 14, 17, 15, 10, 19
- Total count: 5

Interval 20-29:
- Numbers in this interval: 21, 23, 26, 22, 24, 29, 24, 26
- Total count: 8

After counting the numbers, we get the following results:

- Count of numbers in the interval 10-19: 5
- Count of numbers in the interval 20-29: 8

Therefore, the answer is (5, 8).
