1. The following table shows the weights (in gm) of a sample of 100 apples, taken from a large
consignment:
50-60
Weight (in gm
Number of apples
60-70
70-80
80-90
90-100 100-110 110-120 120-130
8
10
12
16
18
14
12
10
(1) Construct the cumulative frequency table.
(ii) Draw the cumulative frequency curve on a graph paper and from it, determine the
median weight of the apples.
Answers
Answer: Median is 92.
Step-by-step explanation:
- Below is the cumulative frequency table.
Weight (in gm) Number of apples cumulative frequency(c.f.)
50-60 8 8
60-70 10 18
70-80 12 30
80-90 16 46
90-100 18 64
100-110 14 78
110-120 12 90
120-130 10 100
- The graph is in in the attached image.
- Hence,the median is 92.
