You can put this solution on YOUR website!
using a normal distribution calculator, this is easy to find.
\n" ); document.write( "here are the results from usig the calculator as https://davidmlane.com/hyperstat/z_table.html
\n" ); document.write( "first with raw scores.
\n" ); document.write( "next with z-scores.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you're working with raw scores, you enter the mean and standard deviation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you're working with z-cores, the mean is 0 and the standard deviation is 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you are looking for an individual score, as in this problem, the standard deviation is appropriate.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you are looking for the mean of a sample of a specific size, then the standard error needs to be used.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "standard error = standard deviation / square root of sample size.\r
\n" ); document.write( "
