Answer 2

Answer:

Explanation:

Let a = 57

Now, the mean of the deviation can be calculated as follows:

where ,fi = frequency of the in the class

di = xi - a

a = assumed mean of the data

= 0.1875

Mean can be calculated as follows:  

where, a = assumed mean of the data

= 0.1875 + 57

= 0.1875 + 57

Mean = 57.1875

       ≈ 57.19 Hence, the mean of the given data is 57.19.
