All of these questions are for my stat's class. I am having a really hard time understanding what needs to be done. I really want to learn what is going on.. I have double the amount of homework than the questions below. I went ahead and took one question from each section to get help with so I can see how to get the answers and see if I can work the similar question in my homework by myself. Any help would be greatly appreciated!
