Question

for the given data 11,15,17,y+1,19,y-2,3 if this mean is 14 then what is value of yy ?? how to find it

Answer 1

Solution:-

Arithmetic Mean = Sum of all the observations/Number of observations

14 = {11 + 15 + 17 + (y + 1) + 19 + (y - 2) + 3}/7
14 = {2y + 66 - 2}/7
14 = {2y + 64}/7
2y + 64 = 14*7
2y = 98 - 64
2y = 34
y = 34/2
y = 17
So, the value of y is 17.
