Answer:
O give Drawn of both types & median = 80.5
Step-by-step explanation:
50-60 3 3 35
60-70 5 8 32
70-80 9 17 27
80-90 12 29 18
90-100 6 35 6
Median = 80 + 10 ( 35/2 - 17)/12
= 80 + 0.42
= 80.42
Median from O give ≈ 80.5

The median from O give ≈ 80.5 .
Step-by-step explanation:
The given table:
Classs Interval Frequency c.f. Ogive
50-60 3 3 35
60-70 5 8 32
70-80 9 17 27
80-90 12 29 18
90-100 6 35 6
Total 35
∴
The cumulative frequency just greater than 17.5 is 29 and corresponding class is 80-90.
∴ l = 80, cf = 17 and h = 10
Median =
∴ Median =
= 80 + 0.42
= 80.42
Hence, the median from O give ≈ 80.5 .
