find the x-value having the normal distribution N(1000,250) that has 10% of the area under that normal curve lying to its right.
\n" ); document.write( "------------
\n" ); document.write( "1st: Find the z-value that has 10% to the right.
\n" ); document.write( "Using a Ti-83 I get InvNorm(0.9) = 1.2816
\n" ); document.write( "-----------
\n" ); document.write( "2nd: Find the corresponding x-value using z = (x-u)/s
\n" ); document.write( "---
\n" ); document.write( "1.2816 = (x-1000)/250
\n" ); document.write( "x-1000 = 250*1.2816
\n" ); document.write( "x-1000 = 320.3879
\n" ); document.write( "x = 1320.3879
