a researcher reports that the ave. salary of sales managers has a mean salary of 43, 800 at alpha= 0.05, test the claim that sales managers earn more than 42, 000 per month. the standard deviation is 5, 400
\n" ); document.write( "------------
\n" ); document.write( "Find the z-value of 42000
\n" ); document.write( "z(42000) = (42000-43800)/5400 = 1/3
\n" ); document.write( "--------------
\n" ); document.write( "P(x > 42000) = P(z > 1/3) = 0.3694
\n" ); document.write( "====================================
