The target thickness of aluminum sheets produced by a machine is 5 mm. A sample of 50 sheets is taken and the thickness of each sheet is determined, resulting in a sample mean thickness of 0.46 mm and standard deviation 0.36 mm. Does this data suggest that true average thickness is something other than the target value? Use a significance level of 0.05. Q7
