14. The time required to prepare a certain specialty coffee at a local coffee shop is uniformly distributed between 30 and 40 seconds. Assuming a customer just ordered one of these specialty coffees, determine the probabilities described below. a. What is the probability that the preparation time will be more than 34 seconds? b. What is the probability that the preparation time will be between 33 and 38 seconds? c. What percentage of these specialty coffees will be prepared within 37 seconds? d. What is the standard deviation of preparation times for this specialty coffee at this shop? a. P(preparation time more than 34 seconds) = (Simplify your answer.) b. P(preparation time between 33 and 38 seconds) = (Simplify your answer.) c. P(preparation time less than or equal to 37) = (Simplify your answer.) d. o = (Round to four decimal places as needed.)
