$8.$ Specifications for a part are ${62}^{\text{'}\text{'}}+1-\mathrm{.}01."$ The part is constructed from a process with a mean of ${62\mathrm{.}01}^{\text{'}\text{'}}$ and a population standard deviation of $\mathrm{.}033.$ The process is normally distributed.

a$.$ Is the process capable?

b$.$ What proportion will meet specifications?

c$.$ Within what values will $95\%$ of sample means of the process fall if the sample size is constant at $5$ and the process is stable?
