A machine is set to pump cleanser into a process at the rate of 10 gallons per minute. Upon inspection, it is
\n" ); document.write( "learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 9.5 to 12.5 gallons per minute.
\n" ); document.write( "------
\n" ); document.write( "Mean = 10---
\n" ); document.write( "6*sigma = 12.5-9.5 = 3
\n" ); document.write( "---
\n" ); document.write( "sigma = 1/2
\n" ); document.write( "-----\r
\n" ); document.write( "\n" ); document.write( "Find the probability that between 10.0 gallons and 11.0 gallons are
\n" ); document.write( "pumped during a randomly selected minute.
\n" ); document.write( "---
\n" ); document.write( "z(11) = (11-10)/3 = 1/3
