Algebra.Com's Answer #193242 by stanbon(75887) ![]() You can put this solution on YOUR website! I don't understand how to do this \n" ); document.write( "find the value of z such that 48% of the distribution lies between it and the mean \n" ); document.write( "----- \n" ); document.write( "There are several ways to work this depending on what tool you \n" ); document.write( "use. You many be using a z-chart or you may be using a calculator \n" ); document.write( "or you may be using Excel, or something else. \n" ); document.write( "---------------- \n" ); document.write( "I use a TI calculator. \n" ); document.write( "I would recommend you draw the normal curve, spot the mean in \n" ); document.write( "the middle of the distribution, pick some point to the right \n" ); document.write( "that appears to have 48% of the population between it and \n" ); document.write( "the mean. Remember that 50% of of the population is to the right \n" ); document.write( "of the mean so your point is pretty far to the right. \n" ); document.write( "---- \n" ); document.write( "Now use your z-chart to find the z-value of that point. \n" ); document.write( "I get invNorm(0.98) = 2.0537.. \n" ); document.write( "Your point is 2.0537 standard deviations to the right of \n" ); document.write( "the mean. \n" ); document.write( "============================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
