Calculate arthmetic mean from the following data: X: 4 5 6 7 8 frequency: 12 10 18 20 24
Answers
Step-by-step explanation:
here u can ur answer...
Given,
- Xi fi
4 12
5 10
6 18
7 20
8 24
To find,
- We have to find the arithmetic mean.
Solution,
We can simply find the arithmetic mean by using the following formula:
Arithmetic mean = ∑fixi/∑fi (*)
Xi fi Xifi
4 12 48
5 10 50
6 18 108
7 20 140
8 24 192
84 538
∑fiXi = 538, ∑fi = 84
Arithmetic mean = 538/84
= 6.40
Hence, the arithmetic mean from the following data: X: 4 5 6 7 8 frequency: 12 10 18 20 24 is 6.40.
