The mean of the following distribution is 6. find p. x 2 4 6 10 p + 5 f 3 2 3 1 2
Answers
The value of p is 7.
Step-by-step explanation:
We are given the mean of following frequency distribution below;
X f
2 3 6
4 2 8
6 3 18
10 1 10
p + 5 2
= 11 =
Now, the mean of frequency distribution is given by the following formula;
Mean, =
6 =
Therefore, the value of p in the above data is 7.
