The following are quality control data for a manufacturing process at Kensport Chemical Company. The data show the temperature in degrees centigrade at five points in time during a manufacturing cycle. The company is interested in using control charts to monitor the temperature of its manufacturing process. Use Table $19\mathrm{.}3.$ The following are quality control data for a manufacturing process at Kensport Chemical Company. The data show the temperature in degrees centigrade at five points in time during a

manufacturing cycle. The company is interested in using control charts to monitor the temperature of its manufacturing process. Use Table $19\mathrm{.}3.$

a$.$ Compute the following for the data.

$\frac{?}{\text{b}\text{a}\text{r}}(R)(to2$ decimals$)$

$\stackrel{}{x}(to2$ decimals$)$

b$.$ What is the upper control limit and lower control limit for the $R$ chart $($to $2$ decimals$)?$

UCL

LCL

Using the results from the $20$ samples and the $R$ chart, what conclusion can be made about the process?

The process variability is in control

c$.$ What is the upper control limit and lower control limit for the $\stackrel{}{x}$ chart $($to $2$ decimals$)?$

UCL

LCL

Using the results from the $20$ samples and the $\stackrel{}{x}$ chart, what conclusion can be made about the process?

The process mean is out of control
