A trade magazine routinely checks the drive-through service times of fast-food restaurants. A 90% confidence interval that results from examining 500 customers in one fast-food chain's drive-through has a lower bound of 165.5 seconds and an upper bound of 168.7 seconds. What does this mean? Choose the correct answer below. O A. There is a % probability that the mean drive-through service time of this fast-food chain is between seconds and seconds. B. The mean drive-through service time of this fast-food chain is seconds % of the time. O C. One can be % confident that the mean drive-through service time of this fast-food chain is between seconds and seconds O D. One can be % confident that the mean drive-through service time of this fast-food chain is seconds.
