Answer 1

Given : marks obtained by 50 students  

52, 16, 18, 20, 42, 48, 39, 38, 54, 58, 47, 37, 25, 16, 42, 49, 36, 35, 53, 21, 30, 43, 56, 34, 33, 17, 22, 24, 37, 41, 40, 50, 54, 56, 54, 36, 38, 42, 44, 56, 17, 18, 22, 24, 17, 48, 58, 23, 29, 58 ​

To Find : Construct a frequency table using equal Intervals taking 16-24 (24 not included) as one of the class-intervals.

Solution:

frequency table
