Find the mean of the following data c.1 0-10,10-20,20-30,30-40-50 f.3,2,5,3,2
Answers
Mean = 24.33
Step-by-step explanation:
We are the following frequency distribution data below;
C.I. f X
0 - 10 3 5 15
10 - 20 2 15 30
20 - 30 5 25 125
30 - 40 3 35 105
40 - 50 2 45 90
Total 15 365
Now, the mean of the frequency distribution is given by the following formula;
Mean, =
=
= 24.33
Hence, the mean of the given data is 24.33.
