Answer:
arithmetic mean of the following data : 5,6,7,8,8,10,10,10,12,12,13,19,19,19,20
The sum of the data = 178
The number of digits = 15

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
