Reflexology is the technique of applying pressure with the thumbs and fingers to specific areas of the feet as a means of diagnosing and alleviating various ailments. Reflexologists contend that the body and all its organs and glands are "mapped" on the foot. For example, the big toe is said to represent the head, the little toe represents the eyes and ears, and the inner portion along the side of each foot corresponds to the spine. Some reflexologists claim to be able to diagnose ailments by looking for painful spots on the foot. For example, they might claim to diagnose throat and tonsil problems by discovering pain on the bottom of the big toe, whereas pain on the bottom of other toes indicates sinus problems.

Hypothesis: Reflexologists can diagnose a wide range of bodily ailments by examining only the bottoms of patients' feet.

Design a good test for this hypothesis. Remember, you are trying to design a test that meets the following conditions:

If the hypothesis is true, the test will provide evidence that is far more likely given that the hypothesis is true. That is, Pr(E|H) >> Pr(E|~H).
If the hypothesis is false, the test will provide evidence that is far more likely given that the hypothesis is false. That is, Pr(E|~H) >> Pr(E|H).
Explain how your test meets these conditions, including how it avoids potential confounders. In other words: imagine someone tells you they're a successful reflexologist. How would you set up an experiment to figure out whether they're right that they can successfully diagnose illness?

**Hint: you can review the features of strong experimental design, but you won't want to blindly list all of the aims of hypothesis testing that the text describes. We want to see if you can figure out which potential confounders would reduce the strength factor of the evidence you collect!
