Answer 2

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}a.m=

no.ofobservation

sumofobservation

So,

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

5

145

= > a.m = 29=>a.m=29
