Question
Solution
Number of students in the interval of 170-175 = 12 Number of students in the interval of 165-170 = 14 Difference = 14 – 12 = 2 Percentage = (Difference/Number of students in the interval of 165-170) × 100 ⇒ Percentage = (2/14) × 100 ⇒ Percentage ≈ 14.28 ≈ 14.3 ∴ Students in the class interval of 170-175 are nearly 14.3% less than the students in the class interval of 165-170
