Parking at a large university can be extremely difficult at times. One particular university is trying to determine the location of a new parking garage. As part of their research, officials are interested in estimating the average parking time of students from within the various colleges on campus. A survey of 338 College of Business (COBA) students yields the following descriptive information regarding the length of time (in minutes) it took them to find a parking spot. Note that the "Lo 95%" and "Up 95%" refer to the endpoints of the desired confidence interval.

Variable         N     Lo 95% CI       Mean      Up 95% CI         SD
Parking Time    338      9.1944         10.466      11.738         11.885

Give a practical interpretation for the 95% confidence interval given above.
◦ We are 95% confident that the average parking time of all COBA students falls between 9.19 and 11.74 minutes.
◦ We are 95% confident that the average parking time of the 338 COBA students surveyed falls between 9.19 and 11.74 minutes.
◦ 95% of the COBA students had parking times of 10.466 minutes.
◦ 95% of the COBA students had parking times that fell between 9.19 and 11.74 minutes.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
