Answer:
Median is 27. Please mark as Brainliest
Step-by-step explanation:
lets us make cf for all the fi's
0-10 - 3
10-20 - 25
20-30 - 36
30-40 - 48
40-50 - 58
50-60 - 64
n = 64
n/2 = 64/2 = 32
since we take median class from the cf greater than n/2
so median class is 20-30
so, l = 20
h = 30 - 20 = 10
cf = 25
f = 11
median = l + (n/2 - cf / f)h
= 20 + ( 32 - 25 / 11) 11
= 20 + 7
= 27
