Specifications for a port for a $3-$D printer state that the port should weigh between $24\mathrm{.}4$ and $25\mathrm{.}4$ ounces. The process that produces

the parts has a mean of $24\mathrm{.}9$ ounces and a standard deviotion of $24$ ounce. The distribution of output is normal. Use Table$-$A$.$

a$.$ Whot percentoge of ports will not meet the weight specs? $($Round your $"z"$ value and final answer to $2$ decimal places.$)$

Answer is complete but not entirely correct.

b$.$ Within whot values will $95\mathrm{.}44$ percent of the somple means of this process foll if somples of $n=7$ ore token and the process is in

control $($rondom$)?($Round your answers to $2$ decimal places.$)$

Answer is complete but not entirely correct.

c$.$ Using the control limits from port b$,$ would the following somple meons be in control? $24\mathrm{.}52,24\mathrm{.}53,24\mathrm{.}44,24\mathrm{.}51,24\mathrm{.}41,24\mathrm{.}39$

This process is in control.

This process is not in control.
