Let's solve each of the problems on the worksheet step by step. The task is to
find the mean of each set of numbers.

🔹 What is the Mean?
The
mean is the average of a set of numbers. To find it:
1. Add all the numbers together.
2. Divide the sum by the total number of values.

We’ll go through each problem:
---
✔ Problem 1:
Numbers: 3, 5, 6, 6, 7, 7, 8
- Sum = 3 + 5 + 6 + 6 + 7 + 7 + 8 =
42
- Count = 7
- Mean = 42 ÷ 7 =
6
✔ Answer: 6
---
✔ Problem 2:
Numbers: 4, 4, 6, 7, 9
- Sum = 4 + 4 + 6 + 7 + 9 =
30
- Count = 5
- Mean = 30 ÷ 5 =
6
✔ Answer: 6
---
✔ Problem 3:
Numbers: 1, 1, 3, 3, 3, 5, 3
- Sum = 1 + 1 + 3 + 3 + 3 + 5 + 3 =
19
- Count = 7
- Mean = 19 ÷ 7 ≈
2.714... (or
19/7)
But since this is likely expecting a decimal or fraction:
➡️
Mean = 19 ÷ 7 ≈ 2.71 (rounded to two decimals)
✔ Answer: 2.71 (or
19/7)

✔ Problem 4:
Numbers: 3, 3, 3, 5, 6, 6, 7
- Sum = 3 + 3 + 3 + 5 + 6 + 6 + 7 =
33
- Count = 7
- Mean = 33 ÷ 7 ≈
4.714...
➡️
Mean ≈ 4.71
✔ Answer: 4.71
---
✔ Problem 5:
Numbers: 5, 6, 8, 8
- Sum = 5 + 6 + 8 + 8 =
27
- Count = 4
- Mean = 27 ÷ 4 =
6.75
✔ Answer: 6.75
---
✔ Problem 6:
Numbers: 3, 5, 6, 6, 6
- Sum = 3 + 5 + 6 + 6 + 6 =
26
- Count = 5
- Mean = 26 ÷ 5 =
5.2
✔ Answer: 5.2
---
✔ Problem 7:
Numbers: 1, 2, 3, 4, 4, 4, 5, 6
- Sum = 1 + 2 + 3 + 4 + 4 + 4 + 5 + 6 =
30
- Count = 8
- Mean = 30 ÷ 8 =
3.75
✔ Answer: 3.75
---
✔ Problem 8:
Numbers: 4, 4, 7, 7, 8
- Sum = 4 + 4 + 7 + 7 + 8 =
30
- Count = 5
- Mean = 30 ÷ 5 =
6
✔ Answer: 6
