Answer 1

$\huge\underbrace\mathfrak{Answer}$

Given:-

17 , 25 , 28 , 35 , 40

• total observation= 5

To Find:-

The Arithmetic mean of

17,25,28,35,40

Solution:-

17 , 25 , 28 , 35 , 40

Here,

=>Total observation=5

=> Sum of observation= 17+25+28+35+40

= 145

We Know that,

$a.m = \frac{sum \: of \: observation}{no. \: of \: observation}$

So,

$a.m = \frac{145}{5}$

$= > a.m = 29$
