Question

Whats the margin of error?

Answer 1

ask a statistician

Answer 2

\[E = \frac{(z_{a/2})^2(.25)}{\sqrt{n}}\text{ i think}\]

Answer 3

.25 can be revamped to be (x/n)*(1-(1/n)) maybe

Answer 4

You know the answer to your own question....

Answer 5

..... wrong formula. This is why a loathe memorization of formulas .... if you cant remember them your outta luck

Answer 6

I agree

Answer 7

\[e=z_{a/2}\sqrt{\frac{p.q}{n}}\]

Answer 8

Does anybody here even know statistics at this level?

Answer 9

:) this is elementary statistics class; they give you the formulas cause the math behind them is so convoluted

Answer 10

Oh, well, that's a relief...

Answer 11

i just aint good at memorizing things at my age :) i forget more than i retain

Answer 12

\[\epsilon = .25 * 1.96/\sqrt{n} = .25 * 1,96./\sqrt{550} = 0.021\]

Answer 13

OOpps,,sorry... actually\[\epsilon = z{(_{\gamma})} / \sqrt{4n} = 1.96/\sqrt{4*550} =0.0418\]
