Calculate median profit.
Answers
Answer:
35
Step-by-step explanation:
Class Frequency
More than 10 -60
More than 20 -56
More than 30 -32
More than 40 -28
More than 50 -20
More than 60 -14
More than 70 -6
By drawing a graph with less than ogive, the two ogives intersect at (35, 30)
Hence, Median = 35
Answer:
Median is 35
Step-by-step explanation:
Class Interval Frequency Cumulative Frequency
10-20 4 4
20-30 24 28
30-40 4 32
40-50 8 40
50-60 6 46
60-70 8 54
70-80 6 60
n/2 = 60/2 = 30
Median class is 30-40
Median = l +[ ( n/2 - cf) / f ] x h
= 30 + [ (30 - 28) / 4 ] x 10
= 30 + [ ( 2 ) / 4 ] x 10
= 30 + [1/2] x 10
= 30 + 5
Median = 35
