1.	Two plants A and B of a factory show the following results about the number of workers and the wages paid to themPlant APlant ANo. workers50006000Average monthly wagesRs. 2500Rs. 2500The variance distribution of wages81100In which plant A or B is there greater variability in individual wages?
Answer» Variation of the distribution of wages in plant A(σ² =18) So, Standard deviation of the distribution A(σ - 9) Similarly, the Variation of the distribution of wages in plant B(σ² =100) So, Standard deviation of the distribution B(σ - 10) And, Average monthly wages in both the plants is 2500, Since The plant with a greater value of SD will have more variability in salary. Hence, Plant B has more variability in individual wages than plant A

Answer»

Variation of the distribution of wages in plant A(σ² =18)

So, Standard deviation of the distribution A(σ - 9)

Similarly, the Variation of the distribution of wages in plant B(σ² =100)

So, Standard deviation of the distribution B(σ - 10)

And, Average monthly wages in both the plants is 2500,

Since The plant with a greater value of SD will have more variability in salary.

Hence, Plant B has more variability in individual wages than plant A
