Elizabeth waited for 6 minutes at the drive thru at her favorite fast food restaurant the last time she visited. She was upset about having to wait that long and notified the manager. The manager assured her that her experience was very unusual and that it would not happen again. A study of customers commissioned by this restaurant found an approximately normal distribution of results. The mean wait time was 226 seconds and the standard deviation was 38 seconds. Find 95% margin of error and use it to create an interval of wait times. Was Elizabeth's wait time unusual?
