Given a level of confidence of 95% and a population standard deviation of 9, answer the following:
\n" ); document.write( "(A) What other information is necessary to find the sample size (n)?
\n" ); document.write( "n = [z*s/E]^2
\n" ); document.write( "You need to know the maximum allowed error.
\n" ); document.write( "-----------------------------------
\n" ); document.write( "(B) Find the Maximum Error of Estimate (E) if n=72. Show all work.
\n" ); document.write( "ME = z*s/sqrt(n) = 1.96*9/sqrt(72) = 2.08
\n" ); document.write( "=====================
