A study found that the mean amount of time cars spent in drive-throughs of a certain fast-food restaurant was 151.7 seconds. Assuming drive-through times are normally distributed with a standard deviation of 34 seconds, complete parts (a) through (d) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). (a) What is the probability that a randomly selected car will get through the restaurant's drive-through in less than 93 seconds? The probability that a randomly selected car will get through the restaurant's drive-through in less than 93 seconds is 0.0421 . (Round to four decimal places as needed.) (b) What is the probability that a randomly selected car will spend more than 211 seconds in the restaurant's drive-through? The probability that a randomly selected car will spend more than 211 seconds in the restaurant's drive-through is. (Round to four decimal places as needed.)
