Question

if f=11,f1x1=2p-52and the mean of any distribution is 6,find the value of p​

Answer 1

i think the correct answer is 59

Answer 2

Answer:

Value of p = 7 .

Step-by-step explanation:

We are given that  ∑$f_1$ = 11, ∑$f_1X_1$= 2p - 52 and mean of any distribution is 6.

And we know that mean for a frequency distribution is given by;

                       ⇒   Mean = $\frac{\sum f_1X_1}{\sum f_1}$

                       ⇒      6    =  $\frac{2p-52}{11}$

                       ⇒   2*p - 52 = 6 * 11

                       ⇒   2*p = 66 - 52

                       ⇒   p  =  $\frac{14}{2}$ = 7 .

Hence, value of p = 7.
