Class Interval 10 - 15 15 - 20 20 - 25 25 - 30 30 - 35 35 - 40 |
Frequency 20 25 30 15 10 5 |
(v)

Class Interval 10 - 15 15 - 20 20 - 25 25 - 30 30 - 35 35 - 40 |
Frequency 20 25 30 15 10 5 |
Cumulative Frequency 20 45 75 90 100 105 |
2. The histogram for a frequency distribution is as shown below.
Answer the following.
(i) Find the class intervals having the greatest and the least frequencies.
(ii) Find the class interval whose frequency is 40.
(iii) What is the frequency of the class interval 30 – 40?
(iv) What is the cumulative frequency of the class interval 30 – 40?
(v) Construct the frequency table of the distribution.
Solution:
(i) The class interval 10 – 20 has the greatest frequency as the rectangle corresponding to the interval has the greatest area, the height being the greatest.
(ii) 20 – 30
(iii) 30
(iv) 50 + 40 + 30 = 120
(v)
Class Interval
10- 20
20 - 30
30 - 40
40 - 50
Frequency
50
