A study found that the mean amount of time cars spent in drive-throughs of a certain fast-food restaurant was 145.3 seconds. Assuming drive-through times are normally distributed with a standard deviation of 32 seconds, complete parts (a) through (d) below. (a) What is the probability that a randomly selected car will get through the restaurant's drive-through in less than 99 seconds? The probability that a randomly selected car will get through the restaurant's drive-through in less than 99 seconds is nothing. (Round to four decimal places as needed.) (b) What is the probability that a randomly selected car will spend more than 184 seconds in the restaurant's drive-through? The probability that a randomly selected car will spend more than 184 seconds in the restaurant's drive-through is nothing. (Round to four decimal places as needed.) (c) What proportion of cars spend between 2 and 3 minutes in the restaurant's drive-through? The proportion of cars that spend between 2 and 3 minutes in the restaurant's drive-through is nothing. (Round to four decimal places as needed.) (d) Would it be unusual for a car to spend more than 3 minutes in the restaurant's drive-through? Why? The probability that a car spends more than 3 minutes in the restaurant's drive-through is nothing, so it ▼ would would not be unusual, since the probability is ▼ less greater than 0.05. (Round to four decimal places as needed.)
