(1 point) A man claims to have extrasensory perception (ESP). As a test, a fair coin is flipped 26 times, and the man is asked to predict the outcome in advance. He gets 23 out of 26 correct. What is the probability that he would have done at least this well if he had no ESP Hint: If he has no ESP, then he's just randomly guessing, right? If he is randomly guessing, what should you use as p, the...

prob 24
One test for claims of extrasensory perception (ESP) involves using Zener cards. Each card shows one of five different symbols (square, circle, star, cross, wavy lines), and the person being tested has to predict the shape on each card before it is selected. Using the Distribution tool below, find each of the probabilities requested for a person who has no ESP and is just guessing. Standard Normal Distribution Mean 0.0 Standard Deviation 1.0 5000 5000 0.0 0,0000 1.0...
