Given : A company has two departments with 42 and 60 employes .Their average weekly wages are Rs.750 and Rs.400.The standard deviation are 8 and 10 respectively
To Find : 1.Which department has a larger bill ?
2.Which department has larger variability in wages
Solution:
Department A Employees = 42
Average weekly wages = 750
Total Wages = 42 * 750 = 31500
Department B Employees = 60
Average weekly wages = 400
Total Wages = 60 * 400 = 24000
31500 > 24000
Department A has larger bill than Department B
Department A Mean = 750
Department A SD = 8
8/750 = 0.0106
Department B Mean = 400
Department B SD =10
10/400 = 0.025
0.025 > 0.0106
department B has larger variability in wages
