Question

The mean of 8, 11, 6, 14, x and 13 is 66. Find the value of the observation x.​

Answer 1

given observations are:

8 , 11 , 6 , 14 , x , 13

total no. of observations:

6

given mean:

66

$\green{SOLUTION}$

$mean = \frac{sum of observations}{no. of observations} \\\\66 = \frac{8+11+6+14+x+13}{6} \\\\66=\frac{52+x}{6} \\\\52+x=396\\\\x = 344$

Hence, the value of x observation will be 344.

Answer 2

Answer:
