- A doctor takes a random sample of 100 patients and measures their intake of saturated fats in their food and the level of cholesterol in their blood. The results are summarised in the table below.
| \backslashbox{Intake of saturated fats}{Cholesterol level} | High | Low |
| High | 12 | 8 |
| Low | 26 | 54 |
Using a \(5 \%\) level of significance, test whether or not there is an association between cholesterol level and intake of saturated fats. State your hypotheses and show your working clearly.
