\n" ); document.write( "Analyzing customer service. The distribution of times that customers spend waiting in line in a supermarket has a mean of 3.6 minutes and a standard deviation of 1.2 minutes. For this distribution find the raw score that corresponds to a z-score of -1.3. \r
\n" ); document.write( "\n" ); document.write( "Here is how I set it up
\n" ); document.write( " -1.3= x-3.6 divided by 1.2
\n" ); document.write( "Then i multiplied both sides by 1.2 giving me the equation of
