A.) Find the point estimate of the proportion of population that said yes: 0.0024 B.) Find the standard error of the estimate: 0.0050 C.) Find the margin of error for a 90% confidence interval: ?????????? D.) Construct 90% confidence interval for the population proportion Lower limit: ??? Upper limit: ??? I'm pretty sure that if I could figure out C, that I'd be able to get D on my own... so can anyone help me with C, please???

What is this post: 1) Call us geeks. 2) Paste in a hw probem. 3) Show no evidence of any attempt to do the confusing parts on your own. This isn't gonna fly dude. Putting aside the nature of this post, I suggest you don't post your friend's homework problems on forums that only you frequent. Help him yourself and if you can't get him to seek out the help himself. I also am not up on the statistics lingo so I don't know how to find what it is asking for :p But from the sound of it the math behind this must be incredibly easy once you understand what it is asking. Read: lecture notes, textbook, etc
