STAT200_ Week 6 Discussion

I’m studying for my Statistics class and need an explanation.

Does drinking coffee (or sodas with caffeine) influence the time someone is awake? Treat the table’s data below as valid (because it’s actually all made-up). These numbers represent how long 10 volunteers stayed awake performing some simple tasks:
1.9, 0.8, 1.1, 0.1, -0.1, 4.4, 5.5, 1.6, 4.6, 3.4

What does the single negative entry indicate?

Explain which formula you selected, then calculate the 95% confidence interval for the average time these volunteers can stay awake. Indicate what software you used for the actual #-crunching. You don’t need to show calculations but state which distribution you used, and why.
