Googling Math Lab or Math Help only resulted in drug addiction sites; aside, realized a Math community with a thriving group of people doesn't really exist. I have my 2nd math exam this coming Thursday. In fact, the exam was today, however figured i'd use my "being held up @ gun-point" story to my advantage and the professor gave me the extra 2 days. (I told him I could take the exam, just that admittedly throughout the weekend the incident was more on my mind than studying for math) Anyways..as I said, the exam is on Thursday so may come back here with a question or two asking for some help. Essentially with me, if I know how to do a math problem, i'll be golden and be able to move on. My 1st exam a month ago I got 100%, however since getting that perfect score got a bit cocky and didn't really open the book (Elemen. Stats by Triola 10th Ed.) Here's the one current question on my mind I can't solve: Ch. 4.4 Probability - Multiplication Rule #12: It is common for public opinion polls to have a "confidence level" of 95%, meaning that there is a 0.95 probability that the poll results are accurate within the claimed margins of error. If six different organizations conduct independent polls, what is the probability that all six of them are accurate within the claimed margins of error? Does the result suggest that with a confidence level of 95%, we can expect that almost all polls will be within the claimed margin of error? Btw, I'm using a TI-83. I'm not really asking for you to solve the problem for me...I just wanna understand it. Hell, yes, gimme the answer too; but I wanna know how to get there.
