A class interval runs from 40 to 60. What is its class width?
- 20
- 10
- 50
- 100
Show answer and solution
Correct answer: A. 20
Width is the upper limit minus the lower limit, 60 minus 40, which is 20.
Class frequencies are 4, 7, 9 and 5. What is the cumulative frequency through the third class?
- 9
- 16
- 20
- 25
Show answer and solution
Correct answer: C. 20
Adding the first three frequencies gives 4 + 7 + 9 = 20.
