It is a very important office sponsored by the Holy See.
I have taken this job very seriously, because I believe that I am the key to increased productivity at the Undergraduate School. Why, by mid-morning, many of my colleagues act as if they were
It is imperative that I restore productivity via a secret naturally-occurring molecule, caffeine........
In order to see if my secret molecule works, I have observed the time, in hours, a random selection of ten of my colleagues
who could stay awake at the extremely long-winded Dean's meeting as soon as it started. Oh, yes, one fell asleep even before the meeting started!

Disclaimer: I was not in the picture above.
Now, I have to complete a report to the Provost's Office on the effectiveness of my secret molecule so that UMUC can file for a patent at the United Provinces Patent and Trademark Office as soon as possible. Oh, yes, I am waiting for a handsome reward from the Provost.....
But I need the following information:
· What is a 95% confidence interval for the time my colleagues can stay awake on average for all of my colleagues?
· Was my secret molecule effective in increasing their attention span, I mean, staying awake? And, please explain.....
OK, take your time, but hurry up !!!
