Given a level of confidence of 95% and a population standard deviation of 14, answer the following:
\n" ); document.write( "--------------
\n" ); document.write( "n = [z*s/E]^2
\n" ); document.write( "--------------------------\r
\n" ); document.write( "\n" ); document.write( "(A) What other information is necessary to find the sample size (n)?
\n" ); document.write( "Ans: The Margin of Error
\n" ); document.write( "---------\r
\n" ); document.write( "\n" ); document.write( "(B) Find the Maximum Error of Estimate (E) if n = 80. Show all work
\n" ); document.write( "Ans:
\n" ); document.write( "80 = [1.96*14/E]^2
\n" ); document.write( "------
\n" ); document.write( "1.96*14/E = sqrt(80)
\n" ); document.write( "----
\n" ); document.write( "E = (1.96*14)/sqrt(80)
\n" ); document.write( "-----
\n" ); document.write( "E = 3.07
\n" ); document.write( "==============
