Question

The mean wages of 216 workers is *79. If one worker left, the mean was calculated again and
was found to be 82. Find the wages of the worker which had left.​

Answer 1

Answer:

88.93

Step-by-step explanation:

As we have 216 workers as given mean wage is 79 .

let everyone has 79 wage

so mean wage is (79*216)/216=79

as now one worker left so we have to make changes so that we can get the demanded wage of 215 workers as given 82. so

let 150 workers have wage=79

65 workers have wage = 88.93

so that (150*79 + 88.93*65)/215 = 82.00

so by this technique we can get a wage of 215 workers .i think its probability related question
