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 more than 5 kilometres?

To find: Number of students who live more than 5 km away.

Look at the table for more than 5 km values in the first column. We have 6, 7, 8, 9, 11, 12 and 14.


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


Frequency of 11 = 1


Frequency of 12 = 2


Frequency of 14 = 1


Add up the numbers, 6 + 5 + 1 + 5 + 1 + 2 + 1 = 21


⇒ There are 21 students from more than 5 km.


Thus, answer is 21.
