3D printers create objects by printing layers of material one on top of the other. Different materials have different mean thicknesses and standard deviations. A particular part is made by stacking 10 layers of material A, followed by 15 layers of material B, and 30 layers of material C. The properties of these materials are shown in the table below (note the units). Assume that the layer thicknesses are all independent. Compute the mean (in mm) and standard deviation (in µm) of the total thickness T of the part. Total thickness T material C Material Average thickness [mm] Standard deviation [µm] material B A 0.2 4 material A B 0.1 3 C 0.05 0.5
