Subject;
We believe that 77% of the population of all Business Statistics students consider statistics to be an interesting topic. Suppose we randomly and independently select 24 students from the population. If the actual percentage is really 77%, find the probability of observing 23 or more students who find statistics to be an interesting topic. Round to six decimal places.
A multiple choice test has 20 questions. Each question has four possible answers with one correct answer per question. What is the probability that a student will answer 10 or more questions correct (to pass) by guessing randomly? Round your answer to three decimal places.
