Good afternoon! I was doing my stat homework and everything was fine as i was reading along the book. Then all of a sudden I felt lost. I imagine this is something I need the calculator to do but I don't know the right steps to input. There is an example that shows how to do it on Pearson but I would like to understand it as well. Any help is appreciated. This is the question.

Plus we never used the TI83 for statistics but for like calculations using exp and logarithm and plotting graphs
