Do people have powers of extrasensory perception (ESP)? Some people claim to have such abilities or to know someone who has them. Some people claim that individuals who consistently get the wrong answer must have ESP too. Other people disbelieve such claims. Imagine that you are to set up an experiment to test the existence of ESP. Each trial in your experiment involves one person privately rolling a fair six-sided die and holding the image of the face of the die that turned up firmly in her mind. In another room, a second person attempts to identify the result correctly without being shown the outcome.

a. What would the null hypothesis be for your test?

b. What would the alternative hypothesis be?
