a set of data is normally distributed with a mean of 1000 and standard deviation of 100.
\n" ); document.write( "what would be the standard score for a score of 933?
\n" ); document.write( "----
\n" ); document.write( "z(933) = (933-1000)/100 = -67/100 = -0.67
\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "what percentage of scores is between 1000 and 933?
\n" ); document.write( "z(1000 + 0
\n" ); document.write( "So, P(933< = x <=1000) = P(-0.67<= z <=0) = 0.2486
\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "what would be the percentile rank for a score of 933?
\n" ); document.write( "Percentile rank = 24%ile
