A Tim Horton's has recently opened up in Edmonton. It is observed that, on any given morning, the time it takes for a car to be served after ordering in the drive-thru follows a normal distribution with / = 7 minutes and o = 2.3 minutes. (a) What is the probability that it takes less than 5.5 minutes for a randomly selected car to be served after ordering? (Round your answer to four decimal places, if needed.) (b) What is the probability that it takes more than 6.9 minutes for a randomly selected car to be served after ordering? (Round your answer to four decimal places, if needed.) CheckFind the area under the standard normal distribution represented by each probability. (Round your answers to 4 decimal places.) (a) P(Z 0.7): (c) P(-1.77
