A town council has published its plans for redeveloping the town centre and residents are being asked whether they approve or disapprove. A random sample of 250 responses has been selected from residents in the four main streets in the town: North, East, South and West Streets. The results are shown in the table.
| Opinion | North Street | East Street | South Street | West Street |
|---|---|---|---|---|
| Approve | 33 | 54 | 42 | 26 |
| Disapprove | 19 | 39 | 28 | 9 |
Test, at the \(5\%\) significance level, whether the opinions of the residents are independent of the streets on which they live.
