Question

if sum of fi=11, sum of fixi=2p+52 and the mean of any distribution is 6,find the value of p.

Answer 1

heyaa,,
__________________________________________________
mean=6
fixi =2p + 52
fi=11
now,,,
from mean formula, mean =€fixi/€fi
here, € Is sigma.
so,
6 =2p +52 /11
66=2p + 52
2p = 66-52
2p =14
p=14/2
p = 7.(ans)

Answer 2

Answer:

Step-by-step explanation:

mean=6

fixi =2p + 52

fi=11

now,,,

from mean formula, mean =€fixi/€fi

here, € Is sigma.

so,

6 =2p +52 /11

66=2p + 52

2p = 66-52

2p =14

p=14/2

p = 7.(ans)
