2. The time required to prepare a certain specialty coffee at a local coffee shop is uniformly distributed between 25 and 45 seconds. Assuming a customer just ordered one of these specialty coffees, determine the probablitites described below. a. What is the probability that the preparation time will be more than 28 seconds? b. What is the probability that the preparation time will be between 32 and 43 seconds? c. What percentage of these specialty coffees will be prepared within 38 seconds? d. What is the standard deviation of preparation times for this specialty coffee at this shop? a. P(preparation time more than 28 seconds) -. (Simplify your answer.) b. P(preparation time between 32 and 43 seconds) = (Simplify your answer.) C. P(preparation time less than or equal to 38) = (Simplify your answer.) d. a (Round to four decimal places as needed.)
