Question

Find the value of x, if the mean of the following is 47. 34, x, 47, 49, 54 and 61.

Answer 1

Answer:

Mean = sum of observations/number of observations

according to the question

$\frac{34 + x + 47 + 49 + 54 + 61}{6} = 47$

$\frac{245 + x}{6} = 47$

$245 + x = 282$

$x = 282 - 245$

$x = 37$

the value of x is 37
