Exercise 3: The tensile strength of a metal part is normally distributed with mean $$40\mathrm{lb}$$ and standard deviation $$8\mathrm{lb}$$. If the lower specification limit is $$34\mathrm{lb}$$ and upper specification limit is $$48\mathrm{lb}$$, Find out the $$\%$$ of parts fail to meet specification?
