Answer :

We may calculate class marks (xi) for each interval by using the relation

xi =

Class size = 0.04

Now taking 0.14 as assumed mean (A), we can calculate as follows:

Mean (x̅) = A + * h

= 0.14 + * (0.04)

= 0.14 – 0.04133

= 0.099ppm

SO, mean concentration of SO2 in the air is 0.099ppm
