You're running an experiment to determine whether people can taste the difference between Coke and Pepsi. Each test subject is given a number of glasses of soda to taste, and will be asked to say which are Coke and which are Pepsi. You're extremely skeptical, and have decided that you will only accept that a person can taste the difference if the ?p-value for their results is less than 0.01. (a) A person is given 10 glasses of soda to taste, and correctly identifies 90%% of them. What is the ?p-value of this outcome? Do you believe that they can taste the difference? (b) A person is given 20 glasses of soda to taste, and correctly identifies 90%% of them. What is the ?p-value of this outcome? Do you believe that they can taste the difference?
