The length of time patients must wait to see a doctor In a local clinic is uniformly distnbuted between 45 minutes and 23 hours. (a) What is the probability of a patient waiting exactly 55 minutes? x {b} What is the probability that a patient would have to wait between ?5 minutes and 2 hours? [Round your answer to two decimal places.) Ex (c) Compute the probability that a patient would have to wait over 2 hours. [Round your answer to two decimal places.) Ex (d) Determine the expected waiting time and its standard deviation (in minutes). (Round your standard deviation to two decimal places.) E(x) = 918.?5 X min or = 30.31 g min
