(correct to one decimal place)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 6.7%.
The number of students whose height is in the class interval 165 - 170 = 14
The number of students whose height is in the interval 150 - 155 = 15
Required percentage = (15 - 14)/15 × 100 = 1/15 × 100 = 6.7%
