Question

4. The length of 40 leaves of a plant are measured correct to one millimetre, and the
obtained data is represented in the following table:
Length (in mm)
Number of leaves
118 - 126
127 - 135
136 - 144
145 - 153
Neun o uw
154 - 162
163 - 171
172-180
(1) Draw a histogram to represent the given data. (Hint: First make the class intervals
continuous]
(ii) Is there any other suitable graphical representation for the same data?
(iii) Is it correct to conclude that the maximum number of leaves are 153 mm long?
Why?​

Answer 1

Answer:

The length of 40 leaves of a plant is measured correct to one millimetre, and the obtained data is represented in the histogram. The other suitable graphical representation of the given data would be a frequency polygon. We have found that the maximum number of leaves has their length lie between 144.5 mm and 153.5 mm. Hence, we can't conclude that the maximum leaves are 153 mm long.
