Answer:
Median is 9
Step-by-step explanation:
Given : xi- 5,7,9,11,13,15,17 frequency 5,7,5,8,2,3,1.
To find : The median of the variate?
Solution :
Creating the data,
x frequency cumulative frequency
5 5 5
7 7 5+7=12
9 5 12+5=17
11 8 17+8=25
13 2 25+2=27
15 3 27+3=30
17 1 30+1=31
Cumulative frequency is adding the frequency.
Total frequency = 5+12+17+25+27+30+31=147
N=31
From
Median is
