Six people are questioned by a researcher and are ranked according to the amount of daily exercise that they undertake. The same six people also have a blood cholesterol test. It turns out that the person who undertakes the most exercise also has the lowest cholesterol level. The person who undertakes the second greatest amount of exercise also has the second lowest cholesterol level, and so on, so that the person with the least exercise has the highest cholesterol. Say this experiment was repeated many times. Find how often on average this inverse matching of rankings of cholesterol level and exercise would occur if in fact there were no connections between cholesterol and exercise. If the experiment is in fact carried out only once and gives the results described, would you be reasonably convinced that there is an inverse association between exercise and cholesterol levels?
