Astudy found that the mean amount of time cars spent in drive-throughs of a certain fast-food restaurant was 157.4 seconds. assuming drive-through times are normally distributed with a standard deviation of 33 seconds, complete parts below: (a) what is the probability that a randomly selected car will get through the restaurant's drive-through in less than 105 seconds? the probability that a randomly selected car will get through the restaurant's drive-through in less than 105 seconds is (round to four decimal places as needed.) (b) what is the probability that a randomly selected car will spend more than 195 seconds in the restaurant's drive-through? the probability that a randomly selected car will spend more than 195 seconds in the restaurant's drive-through is (round to four decimal places as needed)

Atrade magazine routinely checks the drive-through service times of fast-food restaurants. upper aa 9090% confidence interval that results from examining 503503 customers in one fast-food chain's drive-through has a lower bound of 168.7168.7 seconds and an upper bound of 171.7171.7 seconds. what does this mean? choose the correct answer below. a. the mean drive-through service time of this fast-food chain is nothing seconds nothing% of the time. b. one can be nothing% confident that the mean drive-through service time of this fast-food chain is nothing seconds. c. there is a nothing% probability that the mean drive-through service time of this fast-food chain is between nothing seconds and nothing seconds. d. one can be 9090% confident that the mean drive-through service time of this fast-food chain is between 168.7168.7 seconds and 171.1171.1 seconds.

As reported by a recent survey the fast-food restaurant with the best drive through time had a mean time spent in the drie through of u =63.6 seconds. assuming drive through times are normall distributed o =2.9 seconds. complete parts a through d. (a) what is the probability that a randomly selected car will get through the drive through in less than 60.1 seconds? the probability is round to four decimal places as needed. (b) what is the probability that a randomly selected car will spend more than 70 secs. in the drive through. the probability is decimal places. (c) what proportion of cars spend between 60.1 and 70 seconds in the drive through? would it be unusual for a car to spend oe than 70 seconds in the drive through.
