The mean of 10, 12, 16, 20, p and 26 is 17 then the values of p is

Given observations :10,12,16,20,P,26

Number of observations $= 6$

Mean of the observation $= 17$

We know that,

Mean $= \frac{sum of observation}{no . of observation}$

$17 = \frac{10 + 12 + 16 + 20 + P + 26}{6}$

$17 \times 6 = 84 + P$

$102 = 84 + P$

$102 - 84 = P$

$18 = P$
