A data -

• 33, 63, 3, 42 and 9

➤ Option:

A. 30

$\bf \hookrightarrow Mean = \dfrac{Sum \: of \: observation}{Total \: number \: of \: observation}$

Where,

• Total number of observation = 5

➤ Solution:

Using the formula,

$\sf \Longrightarrow Mean = \dfrac{Sum \: of \: observation}{Total \: number \: of \: observation}$

Substitute the values,

$\sf \Longrightarrow Mean = \dfrac{33 + 63 + 3 + 42 + 9 }{5}$

Add the numerator,

$\sf \Longrightarrow Mean = \dfrac{150}{5}$

Divide 150 by 5,

$\sf \Longrightarrow Mean = 30$
