Question

If the arithmetic mean of the following data is 115.86 find the missing value wages No. of workers 110 25 112 17 113 13 117 15 ? 14 125 8 128 6 130 2

Answer 1

918.76

Step-by-step explanation:

Lets consider missing observation as X

Given A.Mean= 115.86

Total obs= 16

sum of observations :- 110+25+112+17+113+13+117+15+X+14+125+8+128+6+130+2=935+X

By formula:-

Arithmetic Mean= Sum of total observation÷total number of observations

Therefore, 115.86=935+X÷16

-->115.86×16=935+X

--> 1853.76= 935+X

--> 1853.76-935= X

--> X= 918.76
