The mean of a distribution is the sum of the data elements divided by the count of the dataset.
<em>The mean of the distribution is 4</em>
The complete table is given as
![\left[\begin{array}{cc}People & Frequency &0 - 2 & 5 & 3 - 5 & 25 & 6 - 8 & 5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DPeople%20%26%20Frequency%20%260%20-%202%20%26%205%20%26%203%20-%205%20%26%2025%20%26%206%20-%208%20%26%205%5Cend%7Barray%7D%5Cright%5D)
The complete question requires that, we calculate the mean of the dataset
First, we calculate the class midpoint
This is the average of the class interval
<u />
<u>For interval 0 - 2, </u>

<u>For interval 3 - 5,</u>

<u>For interval 6 - 8</u>

So, the table becomes
![\left[\begin{array}{ccc}People & x & Frequency &0 - 2 &1 & 5 & 3 - 5 & 4& 25 & 6 - 8& 7 & 5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DPeople%20%26%20x%20%26%20Frequency%20%260%20-%202%20%261%20%26%205%20%26%203%20-%205%20%26%204%26%2025%20%26%206%20-%208%26%207%20%26%205%5Cend%7Barray%7D%5Cright%5D)
The mean is then calculated as:

This gives



Hence, the mean of the distribution is 4

Answer:
A: 66/21
E: 22/7
Step-by-step explanation:
The offered choices reduce to 3 1/7 or to 3. The best approximations of those given are the ones that reduce to 3 1/7.
A: 66/21 = 22/7 = 3 1/7
B: 60/20 = 3
C: 21/7 = 3
D: 45/15 = 3
E: 22/7 = 3 1/7
___
<em>Comment on pi approximations</em>
The ratio 22/7 differs from π by about 0.04%. A better approximation is 355/113, which differs from π by about 0.000008%. The approximation 3.14 differs from π by about 0.05%.
