questions for any statistics people

Well, it asked for a confidence interval. So your answer should have been something like +/- 3.1 or something, where that is the range that you would expect the product to meet specifications. I think you may have had the right idea as posted above by Eclipse, but phrased it a bit wrong.

yeah i don't know..i'm not happy with the teacher just X'ing stuff out and not explaining what i did wrong though.. More irate now knowing i didn't need this stats class and could have taken any other 4 credit class . I'll bring it up tuesday after the test though cause i don't think it's right that she didn't say what was wrong.
