Question

Complete the following cumulative freuqency table :

Class (Height in cm)	Frequency (No. of students)	Less than type frequency
150-153	05	05
153-156	07	05 + $\boxed{1234}$ = $\boxed{1234}$
156-159	15	$\boxed{1234}$ + 15 =$\boxed{1234}$
159-162	10	$\boxed{1234}$ + $\boxed{1234}$ = 37
162-165	05	37 + 5 = 42
165-168	03	$\boxed{1234}$ + $\boxed{1234}$ = 45
	Total N = 45

Answer 1

The cumulative frequency table:

Class (Height in cm)	Frequency (No. of students)	Less than type frequency
150-153	05	05
153-156	07	05 + $\boxed{07}$ = $\boxed{12}$
156-159	15	$\boxed{12}$ + 15 =$\boxed{27}$
159-162	10	$\boxed{27}$ + $\boxed{10}$ = 37
162-165	05	37 + 5 = 42
165-168	03	$\boxed{42}$ + $\boxed{03}$ = 45
	Total N = 45
