Chapter 8, Problem 79CRE

ESP A researcher studying extrasensory perception (ESP) tests 300 students. Each student is asked to predict the outcome of a large number of coin flips. For each student, a hypothesis test using a $5\%$ significance level is performed. If the p-value is less than or equal to $0.05,$ the researcher concludes that the student has ESP. Assuming that none of the 300 students actually have ESP, about how many would you expect the researcher to conclude do have ESP? Explain.
