Floyd Electric is fabricating flanges for a new electrical motor. The following tables shows the diameters of 5 randomly selected samples and in each sample there are of 3 flanges. Use the data provided and calculate the upper and lower control limits of an X-chart. If the next sample diameters are 23.3, 23.9, and 24.8, is the process under control? \begin{tabular}{|l|l|l|l|} \hline & Flange \#1 & Flange \#2 & Flange \#3 \\ \hline Sample 1 & 25.69 & 25.58 & 24.78 \\ \hline Sample 2 & 24.94 & 24.87 & 24.63 \\ \hline Sample 3 & 25.70 & 25.52 & 24.95 \\ \hline Sample 4 & 25.52 & 24.95 & 24.91 \\ \hline Sample 5 & 24.88 & 24.67 & 25.03 \\ \hline \end{tabular}
