- Two breeds of chicken are surveyed to measure their egg yield. The results are shown in the table below.
| \backslashbox{Breed}{Egg yield} | Low | Medium | High |
| Leghorn | 22 | 52 | 26 |
| Cornish | 14 | 32 | 4 |
Showing each stage of your working clearly, test, at the \(5 \%\) significance level, whether or not there is an association between egg yield and breed of chicken. State your hypotheses clearly.
