Answer 2

Correct Question :

Find the value of p from the data 10, 12 ,18, 13 ,p , 17 if mean of data is 15.

$\underline{\underline{\orange{\textbf{Step - By - Step - Explanation : -}}}}$

To Find :

• value of p = ❓

Sᴏʟᴜᴛɪᴏɴ :

Given Data :-

• 10 , 12 , 18 ,13 ,p , 17
• Mean of data = 15

$\sf \: Mean \: of \: Data = \frac{sum \: of \: all \: observations}{number \: of \: all \: observations}$

Number of observations = 6

$\sf\dashrightarrow \: 15 = \frac{10 + 12 + 18 + 13 + p + 17}{6} \\ \\ \sf\dashrightarrow \: 15 \times 6 = 70 + p \\ \\ \sf\dashrightarrow \: 90 - 70= p \\ \\ \sf\dashrightarrow \pink{p = 20}$
