An analysis of monthly wages paid to workers in two firms A and B, belonging to the same industry, gives the following results:

$\begin{matrix} F i r m A & F i r m B N o . o f w a g e e a r n e r s & 586 & 648 M e a n o f m o n t h l y w a g e s & R s . 5253 & R s . 5253 V a r i a n c e o f t h e d i s t r i b u t i o n o f w a g e s & 100 & 121 \end{matrix}$

Solution

(i) Firm A: Number of wage earners ( $n_{1}$ ) = 586

Mean of monthly wages $(_{1})$ =Rs. 5253

Total money wages = Rs. 5253 $\times$ 586 = Rs. 3078258

Team B: Number of wages earners ( $n_{2}$ ) = 648

Mean of monthly wages $(_{1})$ = Rs. 5253

Total money wages = 5253 $\times$ 648 = Rs. 3403944

So, Firm B spends larger amount as monthly wages.

(ii) Since, both the firms have same mean wages, so the firm with greater variance will have more variability in individual wages. Thus, firm B will have more variability in individual wages.
