Answer:

The new mean is 93,076

Explanation:

To solve this question we first need to find the total salary of all the employees combined. For that we will multiply the mean by the number of employees. The mean is 70,000 and number of employees are 39 so the total salary is

(70,000*39)=2,730,000. Now in order to find the new mean we first have to deduct 100,000 from this number and add 1,000,000 to it. (2,730,000-100,000+1,000,000)=3,630,000

In order to find the new mean we will divide 3,630,000 by 39

3,630,000/39= 93,076
