We believe that 80% of the population of all Calculus I students consider calculus an exciting subject. Suppose we randomly and independently selected 24 students from the population. If the true percentage is really 80%, find the probability of observing 23 or more of the students who consider calculus to be an exciting subject in our sample of 24.
