Answer:
56.6
Step-by-step explanation:
CI f cf
40-45 2 2
45-50 3 5
50-55 8 13
55-60 6 19
60-65 6 25
65-70 3 28
70-75 2 30
∴ n = 30, then (n/2) = 15.
55 - 60 is the median class.
Here, l = 55, cf = 13, f = 6, h = 5
(i)
Let x = (n/2 - cf)
= (15 - 13)
= 2
(ii)
Median = l + (x/f) * h
= 55 + (2/6) * 5
= 55 + (10/6)
= 56.6
Therefore, median = 56.6
Hope it helps!
