mean=mu=86
\n" ); document.write( "standard deviation=sigma=4
\n" ); document.write( "For a normal distribution z=(x-mu)/sigma
\n" ); document.write( "We can compute the probability using Excel.
\n" ); document.write( "We have to use a function called NORMDIST in Excel 2007.
\n" ); document.write( "The required probability=NORMDIST(80,86,4,TRUE)=0.066807201
\n" ); document.write( "Answer=0.066807201
