Q2 of 19 Page 184

There are 44 children in class 8B. The list show how far they come from, in kilometres.


Make a frequency table and answer these questions:


How many are from between 5 and 10 kilometres?

To find: Number of students who live between 5 to 10 km.

Look at the table for numbers between 5 and 10. We have 6, 7, 8 and 9.


Now, note down frequencies of each value from the second column.


Frequency of 6 = 6


Frequency of 7 = 5


Frequency of 8 = 1


Frequency of 9 = 5


Add up the numbers, 6 + 5 + 1 + 5 = 17


⇒ There are 17 students who live between 5 to 10 km.


Thus, answer is 17.
