Question

from the following data find the class interval if class length is 5
73, 72, 65, 41, 54,80,50, 46, 49, 53​

Answer 1

Answer:

The frequency distribution table for the given marks can be drawn as:



(i) The class interval (40−49) has the highest frequency and the class interval (90−99) has the lowest frequency.

(ii) In the class interval (30−39), the lower limit is 30 − 0.5 = 29.5 and the upper limit is

39 + 0.5 = 39.5.

(iii) The range of the given distribution is 97− 32 = 65.

Answer 2

Answer:

8

Step-by-step explanation:

Class intervals = Range.

class length

Range = 80 - 41 = 39

Class intervals = 39 = 7.8 ≈ 8
