let the continuous random variable D denotes the diameter of the hole drilled in an aluminium sheet. The target diameter to be achieved is 12.5mm. Random disturbances in the process often result in accuracy. historical data shows that the distribution of D can be modelled by the PDF (d)= 20e-20(d-12.5), d>=12.5. If a part with diameter >12.6mm needs to be scrapped, what is the proportion of those parts? what is the CDF when the diameter is of 11mm? what is...
