Question

If the mean of the following distribution is 6, find the value of P.
Xi 2 4 6 10 P+5 Fi 3 2 3 1 2​

Answer 1

Answer:

sum of fixi = 6+8+18+10+2P+10 = 52+2P

sum of fi = 3+2+3+1+2 = 11

mean = sum of fixi/sum of fi

6 = 52+2P/11

66 = 52+2P

66-52=2P

14=2P

14/2=P

P=7

Answer 2

Answer : 7

Step-by-step explanation :

Mean = sigma xifi / sigma fi
