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 10 kilometres?

To find: Number of students who lives more than 10 km away.

Look at the table for numbers more than 10 in first column ‘Distance (in km)’. We have 11, 12 and 14.


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


Frequency of 11 = 1


Frequency of 12 = 2


Frequency of 14 = 1


Add up the numbers, 1 + 2 + 1 = 4


⇒ There are 4 students who live more than 10 km away.


Thus, answer is 4.
