a Bottle Filling Machine Fills Bottles with 16 Oz

Short Answer

Bottles
A bottle filling machine fills bottles with 16 oz of soda.Each hour,3 bottles are weighed on a precision scale to determine if the process is under control.The following data has been collected from the last 4 hours.Each value in the table represents the weight of an individual bottle.
$$\begin{array} { | l | c | c | c | } \hline \text { Time } & \text { Bottle 1 } & \text { Bottle2 } & \text { Bottle 3 } \\\hline \text { 7AM } & 16.3 & 16.4 & 15.8 \\\hline \mathbf { 8 A M } & 16.0 & 16.2 & 16.4 \\\hline \text { 9 AM } & 15.7 & 16.1 & 16.3 \\\hline \mathbf { 1 0 } \mathbf { A M } & 16.0 & 15.9 & 16.2 \\\hline\end{array}$$
-Assuming this data was collected when the process was operating satisfactorily,construct 3-sigma limits for the mean chart.
