in a test of ESP (extrasensory perception), the experimenter looks at cards that are hidden from the participant. Each card contains either a star, a circle, a wavy line, or a square. An experimenter looks at each of 100 cards in turn, and the participant tries to read the experimenter's mind and name the shape on each. The probability that the participant gets at least 30 correct if the participant does NOT have ESP and is just guessing is closest...

In a test of ESP (extrasensory perception), the experimenter looks at cards that are hidden from the subject. Each card contains either a star, a circle, a wavy line, or a square. An experimenter looks at each of 100 cards in turn, and the subject tries to read the experimenter's mind and name the shape on each. What is the probability that the subject gets 35 or more correct if the subject does not have ESP and is just guessing?

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...
