Question

Find the mean of the group

Answer 1

Answer:

Mean = 328.15

Step-by-step explanation:

Given that,

The sum of fx = 30,847

The sum of f = 94

We need to find the mean of the group. We know that,

$\text{Mean}=\dfrac{\Sigma fx}{\Sigma f}$

Put all the values,

$\text{Mean}=\dfrac{30847}{94}\\\\=328.15$

So, the mean of the group is equal to 328.15.
