In a retail market, fruit vendors were selling mangoes kept in packing boxes. These boxes contained varying number of mangoes. The following was the distribution of mangoes according to the number of boxes.Find the mean number of mangoes kept in a packing box. Which method of finding the mean did you choose?

Explanation

Here, we can see that, intervals are not continuous.

Thers is a gap of `1` between each interval.

So, we can add `1/2` in upper limit and subtract `1/2` in lower limit.

Now, with these new intervals, we can construct a table.
Here, we can use step deviation method to find the mean of given data.

Please refer to video for constructing complete table.


We know, Mean,`(barX) = a+(sumf_iu_i)/(sumf_i)**h`
