Answer:
Step-by-step explanation:
Before=
average Mean = Rs 8
Standard deviation (s.d) = Rs.1
After =
average Mean = Rs 12
Standard deviation (s.d) = Rs.1.5
Coefficent of variation = S.d / Mean * 100%
Before=
average Mean = Rs 8
Standard deviation (s.d) = Rs.1
Coefficent of variation = S.d / Mean * 100%
= 1/8 * 100
= 12.5 %
After =
average Mean = Rs 12
Standard deviation (s.d) = Rs.1.5
Coefficent of variation = S.d / Mean * 100%
= 1.5/12 * 100
= 12.5 %
Wages increased
