Question

Suppose that all 75 employees of a company received a raise of $150 per month? How would this affect the mean salary of all employees in this company?

Answer 1

Answer:

Mean Salary of all employees will be increase by $150.

Explanation:

$150 raise of all 75 employees will be averaged and result in the $150 increase in the mean of all employees salary.

Suppose:

The Sum of all Employees salary = $1,500,000

The Mean of all Employees salary = $100,000 / 75

The Mean of all Employees salary = $20,000

The Sum of all Employees salary after raise = $1,500,000 + ( 75 x 150 )

The Sum of all Employees salary after raise = $1,511,250

The Mean of all Employees salary after raise = $1,511,250 / 75

The Mean of all Employees salary after raise = $20,150

Hence Proved that Mean Salary of all employees will be increase by $150.
