Question

A student who claims he can tell cola A from cola B is blindly tested with 20 trials. At each trial, cola A or cola B is randomly chosen and presented to the student, who must correctly identify the cola. The experiment is designed so that the student will have exactly 10 sips from each cola. He gets 6 identifications right out of 20. Can he tell cola A from cola B at the 0.05 level of significance? Explain.
