In order to see if my secret molecule works, a random sample of ten colleagues who had the coffee before the Dean's meeting was selected. I have observed the time, in hours, for those 10 colleagues to 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! 1.9 0.8 1.1 0.1 -0.1 4.4 5.5 1.6 4.6 3.4 . 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. 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.....
