The bus you take every morning is equally likely to be anywhere from 2 minutes early to 15 minutes late. What is the probability that the bus is more than five minutes late?
\n" ); document.write( "-------------------------------
\n" ); document.write( "The range is 15--2 = 17 minutes.
\n" ); document.write( "6 sigma covers the range
\n" ); document.write( "So, 6 sigma = 17
\n" ); document.write( "sigma = 17/6
\n" ); document.write( "------------
\n" ); document.write( "The middle value is 9 minutes.
\n" ); document.write( "---------------------------------------
\n" ); document.write( "Find the z-score of 5:
\n" ); document.write( "z(5) = (5-9)/(17/6) = -24/17
\n" ); document.write( "-----------------------
\n" ); document.write( "P(x>5) = P(z>(-24/17)) = 0.9210
\n" ); document.write( "=======================================
