In a retail market, fruit vendor 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?

Answer :

We may observe that the class intervals are not continuous. There is a gap between two class intervals so we have to add from lower class limit of each interval.

Class size (h) of this data = 3

Now taking 57 as assumed mean, we can calculate as follows:

Mean = A + * h

= 57 + * 3

= 57 +

= 57 + 0.1875 = 57.1875

= 57.19

Number of mangoes kept in packing box is 57.19
