Answer :

Mean wages of both the factories are the same, i.e., Rs. 5300.

To compare variation, we need to find out the coefficient of variation (CV).

We know, CV = , where SD is the standard deviation.

The variance of factory A is 100 and the variance of factory B is 81.

Now, SD of factory A = And, SD of factory B = Therefore,

The CV of factory A = The CV of factory B = Here, the CV of factory A is greater than the CV of factory B.

Hence, factory A has more variation.
