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( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
