Dr Icit ESP Experiment

1.) Dr. Icit is conducting and ESP experiment. A computer is used to randomly select and present a number one of five pictures (house, boat, shoe, people, or horse). The subject must determine which picture is being presented on the computer screen (being viewed only by the researchers). The researcher records the answers as either correct or incorrect.
a.) What is the probability that a subject would guess correctly on the very first trial?
b.) What is the probability that a subject would guess more than 36 correct in a series of 60 trials?
c.) What is the probability that a subject would guess exactly 30 correct out of 60 trials?

2.) For a normal population with a mean=600 and a standard deviation=30.
a.) What is the probability of obtaining a sample mean greater than 606 for a sample of n=9?
b.) What is the probability of obtaining a sample mean greater than 606 for a sample of n=25?
c.) What is the probability of obtaining a sample mean that is more than 593 and less than 607 for a sample of n=36?

Solution Summary

The solution calculates probability for trials as well as interprets the sample mean for a normal population.
