Answers
Answer:
If 2930 is the mean of salaries of 15 workers and if a new worker joined the company with a salary of 3138, then the new mean of salaries of 16 workers is 2943
Step-by-step explanation:
Given
Mean of salaries of 15 workers = 2930
That is,
Sum of salaries of 15 works / 15 = 2930
Sum of salaries of 15 workers = 2930*15 = 43950
If a new worker joined,
Given salary of the new worker= 3138
New mean of salaries of 16 workers = sum of salaries of 16 workers / 16
Sum of salaries of 16 workers = sum of salaries of 15 workers + salary of new worker
= 43950 + 3138
= 47088
So new mean = 47088/16 = 2943
So the mean of salaries of 16 workers is 2943
Answer:
2943
Step-by-step explanation:
difference between new salary and mean salary
= 3138-2980
=208
new mean = 2930+(208/16)
= 2930+13
= 2943
Therefore, the new mean is RS. 2943
