Answer 1

Answer:

Marksobtained No.of students

(f) Cumulativefrequency

Here, N=50, then

2N = 250 =25

We can see, 25 is nearest to cumulative frequency 35 which has class interval 40−60

∴ Median class =40−60.

⇒ In frequency table we can see class 40−60 has highest frequency 25.

∴ Modal class =40−60
