2.) A mаnufаcturer prоduces crаnkshafts fоr an autоmobile engine.  The crankshaft’s diameter (3cm) is of interest because it is likely to have an impact on warranty claims.  A random sample of n=15 shafts is tested and .  It is known that the true deviation in wear is 0.9cm and the wear is normally distributed.  Is there evidence that the diameter of the crankshafts is not 3cm?  Show all work!
