Hello
Can you help me please about the next exercise:
The average daily wage of an employee in factory A is 300 dollars, and the standard deviation of wage in the same factory is 50 dollars.
Factory B, which employs three times more than number of employees in factory A (it means - if there are 100 employees in factory A, so in factory B there are 300 employees), pays their employees a standard salary of 200 dollars per day.
Therefore, the standard deviation of the wage of all employees in the two factories is:
a. 50 dollars.
b. 25 dollars.
c. 625 dollars.
d. 2500 dollars.
My incomplete solution:
Therefore, in factory B there are 3*b employees.
And if I understood correctly, the average in factory B is 200 dollars.
I still can't reach a solution, I don't know... maybe I'm in the wrong direction? or I did something wrong?
Thanks a lot!
*Sorry if my english is bad, I will explain again and again if you didn't understand*
