Use the appropriate normal distribution to approximate the resulting binomial distribution. Jorge sells magazine subscriptions over the phone. He estimates that the probability of his making a sale with each attempt is 0.08. What is the probability of Jorge making more than 14 sales if he makes 80 calls? (Round your answer to four decimal places.)
