Answer»

When each worker is given a hikes of 10% in wages both the mean and standard deviation values will be affected.

New Mean = Rs. 200 + 10 % of Rs. 200

= Rs. 200 + \(\frac{10}{100}\) x 200 = Rs. 220

New Standard Deviation

= Rs. 40 + 10% of Rs. 40 = Rs. 40 + \(\frac{10}{100}\) x 40 = Rs. 44.
