Vedclass · Answer

(B) To find the modal class,we first convert the cumulative frequency distribution into a standard frequency distribution table:						Class Interval			Frequency							$0-10$			$3$							$10-20$			$12 - 3 = 9$							$20-30$			$27 - 12 = 15$							$30-40$			$57 - 27 = 30$							$40-50$			$75 - 57 = 18$							$50-60$			$80 - 75 = 5$			The modal class is the class interval with the highest frequency.From the table,the highest frequency is $30$,which corresponds to the class interval $30-40$.Therefore,the modal class is $30-40$.
