Question

Xi 3,4,5,7,10 fi 3,4,8,5,10
Arithmetic mean of the following frequency distribution.

Answer 1

Answer:

the solution is above....

Answer 2

We recall that Arithmetic mean $M=\frac{\sum X_iF_i}{\sum F_i}$.

Given: $X_i$ 3,4,5,7,10 and $F_i$  3,4,8,5,10

$\sum X_iF_i=200\\\sum F_i=30\\\frac{\sum X_iF_i}{\sum F_i}=\frac{200}{30}\\=\frac{20}{3}$
