Question

find the value of P when the mean of the following data is 21.6


xi 6 12 18 24 30 36
fi 5 4 p 6 4 6​

Answer 1

Step-by-step explanation:

First multiply xi and fi and by doing that we get.

6×5=30

12×4=48

18×p=18p

24×6=144

30×4=120

36×6=216

add the products

30+48+18p+144+120+216=558+18p

558+18p/126=21.6

558+18p=2721.6

p=120.2
