A simple random sample of 72 face-to-face meetings held in March 2020 was selected, and the mean length of this sample of 72 meetings was 48 minutes with a standard deviation of 14.3 minutes. An independent simple random sample of 61 Zoom meetings held in March 2020 was selected, and the mean length of this sample of 61 meetings was 53 minutes with a standard deviation of 12.8 minutes. If appropriate, use this information to calculate and interpret a 95% confidence interval for the difference in the mean length of all face-to-face meetings and the mean length of all Zoom meetings.
