Not clear what is to be done except probably test the hypothesis at the 0.05 level, which is a right-tailed test here.
\n" ); document.write( "critical value is |z|>1.645
\n" ); document.write( "z=(75.1-72)/6/sqrt(16)=3.1*4/6=12.4/6=2.07
\n" ); document.write( "because z>1.645, the conclusion may be drawn that the population mean is greater than 72. \n" ); document.write( "
