Let’s solve this step by step.

First, we need to understand what the data is showing. Mr. Adam listed how many books each student read. The numbers are:

3, 6, 4, 5, 2, 3, 6, 3, 5, 6
2, 6, 6, 4, 4, 6, 4, 7, 5, 4

That’s 20 numbers total — so there are 20 students in the class (we’ll use that for question 7).

Now, let’s count how many times each number appears. That will help us answer all the questions.

Let’s list the numbers from smallest to largest and count them:

- 2 books: appears 2 times → (positions: 5th and 11th)
- 3 books: appears 3 times → (1st, 6th, 8th)
- 4 books: appears 5 times → (3rd, 14th, 15th, 17th, 20th) → wait, let me recount carefully!

Actually, let’s go through the full list again and tally:

List:
Row 1: 3, 6, 4, 5, 2, 3, 6, 3, 5, 6
Row 2: 2, 6, 6, 4, 4, 6, 4, 7, 5, 4

Let’s make a frequency table:

Number of books | How many students (count)
----------------|--------------------------
2 | ?
3 | ?
4 | ?
5 | ?
6 | ?
7 | ?

Go one by one:

Count of 2s:
→ Row 1: position 5 = 2
→ Row 2: position 1 = 2
Total = 2

Count of 3s:
→ Row 1: positions 1, 6, 8 → three 3s
→ Row 2: none
Total = 3

Count of 4s:
→ Row 1: position 3 = 4
→ Row 2: positions 4, 5, 7, 10 → four more? Wait, let's list:

Row 1: 3, 6, 4, 5, 2, 3, 6, 3, 5, 6 → one 4
Row 2: 2, 6, 6, 4, 4, 6, 4, 7, 5, 4 → that’s four 4s in row 2? Let’s index:

Row 2:
1: 2
2: 6
3: 6
4: 4 ← first
5: 4 ← second
6: 6
7: 4 ← third
8: 7
9: 5
10: 4 ← fourth

So row 2 has four 4s? But wait — position 4,5,7,10 → yes, four.

Plus row 1 had one → total 5 fours.

Wait — let me write all 20 numbers in order and mark counts:

Full list with indices:

1: 3
2: 6
3: 4
4: 5
5: 2
6: 3
7: 6
8: 3
9: 5
10: 6
11: 2
12: 6
13: 6
14: 4
15: 4
16: 6
17: 4
18: 7
19: 5
20: 4

Now count:

- 2: positions 5, 11 → 2
- 3: positions 1, 6, 8 → 3
- 4: positions 3, 14, 15, 17, 20 → 5
- 5: positions 4, 9, 19 → 3
- 6: positions 2, 7, 10, 12, 13, 16 → 6
- 7: position 18 → 1

Double-check total: 2+3+5+3+6+1 = 20 → correct.

Now answer each question:

1. How many students read 5 books?
→ From above: 3

2. How many students read 6 books?
→ 6

3. How many more students read 4 books than read 2 books?
→ 4 books: 5 students
→ 2 books: 2 students
→ 5 - 2 = 3

4. What was the highest number of books read by a student?
→ Look at the numbers: max is 7

5. How many students read fewer than 4 books?
→ Fewer than 4 means 2 or 3 books
→ 2 books: 2 students
→ 3 books: 3 students
→ Total: 2 + 3 = 5

6. How many books were read by the most students?
→ Which number has the highest count?
→ 6 books was read by 6 students → that’s the highest frequency
→ So answer is 6

7. How many students were in Mr. Adam’s class?
→ We counted 20 numbers → 20

All answers verified.

Final Answer:
1. 3
2. 6
3. 3
4. 7
5. 5
6. 6
7. 20
