Question

if the mean of 20, 14,16,19,p and 21 is 27 then find the value of p

Answer 1

(20+14+16+19+p+21)/6 = 27,

70+p=27×6,

70+p=162,

then

p=162-70,

p=92

Answer 2

Thank you for asking this question, here is your answer:

First we solve this:

Given, Mean of 20 , 14 , 16, 19, p and 21 is 27

 Mean = Sum of obs./ no.of obs.

27 = 20+14+16+19+p+20/6

27(6) = 69 + p

162 = 69+p  

p = 162 - 69

p = 93
