Algebra.Com's Answer #302351 by stanbon(75887) ![]() You can put this solution on YOUR website! A 90% confidence interval for a population mean is determined to be 800 to 900. If the confidence is increased to 95% confidence while the sample statistics and sample size remain the same, the confidence interval for mui \n" ); document.write( "------------------------ \n" ); document.write( "If confidence is increased from 90 to 95, z increases, \n" ); document.write( "so ME increases, so the CI becomes wider. \n" ); document.write( "---------------------------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( "A. becomes narrower \n" ); document.write( "B. becomes .05 \n" ); document.write( "C. does not change \n" ); document.write( "D. becomes wider \n" ); document.write( "E. becomes .025 \n" ); document.write( " \n" ); document.write( " |
