According to a survey, 70% of adults believe that every university student should take at least one course in ethics. Assume that this percentage is true for the current population of adults. a) Find the probability that the number of adults in a random sample of 14 who hold this view is more than 12. b) For 200 randomly selected adults, what is the approximate probability that between 130 and 160, inclusive, believe that every university student should take at least one course in ethics? (Hint: Use Normal approximation to the binomial).
