I do not know what the difference between these are:
\n" ); document.write( "Is this the right answer to this (2.326*500/10)² = 13,525.69
\n" ); document.write( "or would this be the way to do this ((2.326*500)/10)² =
\n" ); document.write( "Looking to find the number to survey, using 98% confidence level and a deviation of 500 and be wtihin 10 plus or minus.
\n" ); document.write( "------
\n" ); document.write( "Since E = z
\n" ); document.write( "n = [z*s/E]^2
\n" ); document.write( "----
\n" ); document.write( "n = [2.326*500/10]^2
\n" ); document.write( "---
\n" ); document.write( "n = 13525.69..
\n" ); document.write( "---
\n" ); document.write( "Round up to 13,526
