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
------------
Find the z-value of 42000
z(42000) = (42000-43800)/5400 = 1/3
--------------
P(x > 42000) = P(z > 1/3) = 0.3694
