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,
[tex]\text{Mean}=\dfrac{\Sigma fx}{\Sigma f}[/tex]
Put all the values,
[tex]\text{Mean}=\dfrac{30847}{94}\\\\=328.15[/tex]
So, the mean of the group is equal to 328.15.
