6 A random sample of residents in a town took part in a survey. They were asked whether they would prefer the local council to spend money on improving the local bus service or on improving the quality of road surfaces. The responses are shown in the following table, classified according to the area of the town in which the residents live.
| Area 1 | Area 2 | Area 3 |
| Local bus service | 73 | 36 | 30 |
| Road surfaces | 47 | 44 | 20 |
Using a \(5 \%\) significance level, test whether there is an association between the area lived in and preference for improving the local bus service or improving the quality of road surfaces.
