Question

Following is the
data of height (in cm) of student of class 6:
155
147
172
172
159
147
172
157
172
157
159
159
172
155
a) Draw a frequency table.
(2)
b) What is the shortest height?
(1)
c) Whatis the tallest height?(1)
d) Which is the most repeated height? Find tffds many students of that height?(1​

Answer 1

Answer:

b shortest hieght =147 cm

c tallest hieght =172 cm

d 172 cm

Answer 2

Solution :
With the given data we can see that the minimum value is 150
150
and the maximum value is 173
173
.
So, we can create class intervals 150−155,155−160,160−165,165−170,170−175
150
-
155
,
155
-
160
,
160
-
165
,
165
-
170
,
170
-
175

Then, we can mark the frequency of the number of students with each class interval.
Please refer to video for complete frequency distribution table.
From the frequency distribution table, we can see that,
Number of students having height less than 165
165
cms =12+9+14=35
=
12
+
9
+
14
=
35

Number of students having height less than 165
165
cms =10+5=15
=
10
+
5
=
15

Thus, we can conclude that 70%
70
%
of the students have height less than 165
165
cms.
Hopefully I answered it right!
Please mark me the brainliest!
