CAPE Applied Mathematics Unit 2 · 2010 · Paper 2 · Question 4(b)(iii)

A table shows the distribution of the number of employees working overtime and their home distance from the workplace in kilometres.

Using a 5% significance level, determine whether the number of employees who work overtime is independent of the distance of their home from the workplace. Clearly state your conclusion of the test.

This question uses a figure or table from the paper — you'll see it when you practise.
