Homework Help: statistics

Posted by Karen on Monday, May 9, 2011 at 12:47pm.

Your friend David works for an online magazine and calls you late one night. He says “Dude(tte), can you help me out? I’m putting together an article and the submission deadline is in an hour. I want to quote an opinion poll result my publisher gave me, but they didn’t give me the margin of error, you know that plus-minus thingy they always give with the main opinion poll result. You’re taking that Stat class right? Here’s the info I have; the magazine asked 185 people if they had ever watched an episode of the original “Star Trek” TV series. According to the magazine 46% said yes. Can you help? Hey, are you still awake?”
What would be an acceptable margin of error for this survey result? Write a sentence below that David could use in his article that summarizes the results.
