Question

Find the mean of the group

Answer 1

Mean = 328.15

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}=(\Sigma fx)/(\Sigma f)`

Put all the values,

`\text{Mean}=(30847)/(94)\\\\=328.15`

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