Q. 55.0( 1 Vote )

If the mean of the following frequency distribution is 8, find the value of p.

Answer :

Let’s draw the table and calculate the relative value of variables ∑xi×fi

By putting the formula of mean we get;

Mean = (given)

So we have,

303 + 9P = 8 (41 + P)

303 + 9P = 328 + 8P

9P-8P = 328-303

P = 25

Hence the value of the P is 25.
