Need help with Kaplan University Statistics

I have completed the assignment. I need someone to review it and make changes. I need the PowerPoint to explain how I received the answer in a professional manner. I really need to ace this, so any help would be greatly appreciated. Kaplan has made changes to the rubric and have changed some of the questions. In general relating to the numbers in the equations, they will be different. Also in question 1b, I need to explain what I learned from the metrics, all of them. This is worth 20 points in itself.
