Question

(i) Find fidi, if d = 1.2 and fi= 25.
statistics​

Answer 1

The value of $fi.di$ is $30$

Step-by-step explanation:

Given,

If $d = 1.2\ and\ fi= 25$ then $fi.di=?$

Here,

$fi.di$ means the product between $fi$ and $di$

So, $fi.di$

$=1.2\times 25$

$=30$

Hence, The value of $fi.di$ is $30$

Answer 2

The value of $f_id_i=30$.

Step-by-step explanation:

Given : If $d_i= 1.2$ and $f_i=25$ statistics​.

To find : The value of $f_id_i$ ?

Solution :

$f_id_i$  is written as product of $f_i$ and $d_i$,

i.e. $f_id_i=f_i\times d_1$

$f_id_i=25\times 1.2$

$f_id_i=30$

Therefore, the value of $f_id_i=30$.
