No. of students 5
6 4 1

Answer 1

Explanation:

Range = Upper limit of the highest class interval − Lower limit of the lowest class intervalor, Range = 34.5 − 4.5 = 30 Coefficient or Range = H − L H + L = 34.5 − 4.5 34.5 + 4.5 = 30 39 H−LH+L=34.5−4.534.5+4.5=3039 = 0.769 Hence, the range is 730 marks and coefficient of range is 0.769.Read more on Sarthaks.com - https://www.sarthaks.com/1053945/evaluate-range-coefficient-range-the-marks-marks-1014-1519-2024-2529-3034-students
