A trade magazine routinely checks the drive-through service times of fast-food restaurants. A 95% confidence interval that results from examining 755 customers in one fast-food chain's drive-through has a lower bound of 161.1 seconds and an upper bound of 164.3 seconds. What does this mean? Choose the correct answer below. O A. There is a 95% probability that the mean drive-through service time of this fast-food chain is between 161.1 seconds and 164.3 seconds. O B. One can be 95% confident that the mean drive-through service time of this fast-food chain is between 161.1 seconds and 164.3 seconds. OC. The mean drive-through service time of this fast-food chain is 162.7 seconds 95% of the time. O D. One can be 95% confident that the mean drive-through service time of this fast-food chain is 162.7 seconds.
