Thread: Confidence Intervals

I got great help with the last problem I had I was wondering if you guys could tell me if i answered these right?
And how to fix the ones that are wrong
I dont quite know what I'm supposed to use on the calculator for the one with the ?mark

I know there are multiple problems but since I'm more asking if im correct or not in what I have I am hoping its okay





If those dont show up here are the links

Please don't post more than two questions in a thread. Otherwise the thread can get convoluted and difficult to follow. Start new threads as necessary for remaining questions. eg. If you have five questions, post two of them in two threads and start a new thread for the remaining one etc.

And if the question has more than two parts to it, it is best to post only that question and its parts in the thread and start a new thread for other questions.

Also, this looks like it's an assignment that counts towards your final grade. MHF policy is to not knowingly help with such questions.
