[From Chapter 7 problem 21] One classical experiment on ESP (extrasensory perception) tests for the ability of an individual to show telepathy – to read the mind of another individual. This test uses five cars with different designs, all know to both participants. In a trial, the “sender” sees a randomly chosen card and and concentrates on its deign. The “receiver” attempts to guess the identity of the card. Each of the five cars is equally likely to be chosen, and only one card is the correct answer at any point.
(a) If someone is guessing, what percent would you expect she/he to get correct?
(b) We want to test if someone’s success rate if different from the guessing success rate. Write the two hypothesis in symbols.

Technifi Expert’s Answer:
(a) If a person is guessing then:
Probability of getting correct = 1/5 = 0.20
The person would be correct 20% times.
(b) The hypotheses in symbols will be:
Ho: p = 0.20
Ha: p 0.20
