Assume that the hourly cost to operate a commercial airplane follows the normal distribution with a mean of $3,985 per hour and a standard deviation of $440.
\n" ); document.write( "----------------------------
\n" ); document.write( "What is the operating cost for the lowest 2% of the airplanes? (Round z value to 2 decimal places and round final answer to nearest whole dollar.)
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "Find the z-value with a left-tail of 2%
\n" ); document.write( "invNorm(0.02) = -2.054
\n" ); document.write( "Find the corresponding x-value using x = z*s + u
\n" ); document.write( "----
\n" ); document.write( "x = -2.054*440+3985 = $3081.35\r
\n" ); document.write( "\n" ); document.write( "Operating cost $3081.35
\n" ); document.write( "--------------
