Answers
Step-by-step explanation:
In order to find the mean value, we will use direct method because the numerical value of f and x are small.
are small.Find the midpoint of the given interval using the formula.
are small.Find the midpoint of the given interval using the formula.Midpoint (x) = (upper limit + lower limit)/2
class interval. f x(mid point) fx
0-2 1 1 1
2-4. 2 3 6
4-6. 1 5 5
6-8. 5 7 35
8-10 6 9 54
10-12 2 11 22
12-14 3 13 39
sum of f = 20 sum of fx =162
Mean = sum of fx/sum of f
=162/20
=8.1
