Answer:

145-153

Step-by-step explanation:

constructing cf table

height number of stds cf

118-126 3 3

127-135 5 9

136-144 9 17

145-153 12 29

154-162 5 34

163-171 4 38

172-181 2 40

N=40

median=(n+1/2)term

=( 40 + 1/2)term

=(20.5)term

In CF table 29 is just greater than 20.5

so median height of the children of the locality is 145-153

latha6171: thank you so much

Hey dear...
here is your answer..
❤❤❤❤❤❤❤❤❤
first u find out the c.f
C-I...... F...... CF......
118-126. ...3.... ....3
127-135.. ...5.... .....5+3=8
136-144.. ...9.... .....8+9=17
145-153.. ....12... ....17+12=29
154-162.. ....5.. .....29+5=34
163-171... 4... .......34+4=38
172-180... 2... .........38+2=40..

n=40...
h=8...
Median :- L + {n - CF } ×h..
-----------
2
--------------
F

145 + ( 40 - 17 ) × 8
-----------
2
----------
12

145 + (20 - 17) × 8
------------
12

145 + ( 3 ) × 8
-----
12

145 + 24
----
12

145 + 2

= 147..

hence ; Median = 147...

Hope! it's help ...

PLZ MARK ME AS BRAINLIST...

THANK YOU.....

latha6171: thank you so much for answering

latha6171: I felt that the other students who may have a doubt in this particular question may prefer to see a well organised Cumulative frequency table ..... so I marked the perfect answer by belthapa1977 as brainliest ... I dont understand why you people fight over such petty issues... your comments are so disapproving ❗
