Statistics final…. | Mathematics homework help

This is a 20 question final that is worth 300 points. I have to have an A on this to pass the course.

The last two assignments I posted, that I needed help on, almost failed me so this is extremely important.

Some questions, the work must be shown to get credit for them and are clearly marked.

So please, if your not 100 percent sure on how to do statistics, dont help.
