The time required to prepare a certain specialty coffee at a local coffee shop is uniformly distributed between 20 and 60 seconds. Assuming a customerjust ordered one of these specialty coffees, determine the probabilities described below. a. What is the probability that the preparation time will be more than 35 seconds? b. What is the probability that the preparation time will be between 31 and 46 seconds? 0. What percentage of these specialty coffees will be prepared within 41 seconds? d. What is the standard deviation of preparation times for this specialty coffee at this shop? a. P(preparation time more than 35 seconds) = D (Simplify your answer.) b. P(preparation time between 31 and 46 seconds)= D (Simplify your answer.) c. P(preparation time less than or equal to 41) = I: % (Simplify your answer.) d. o = D (Round to four decimal places as needed.)
