Five data entry operalors work at the data processing department of the Birmingham Bank. Each day for 30 days, the number of defective records in a sample of 250 records typed by these operalors has been noted, as follows: \begin{tabular}{cc|cc|cc} \hline \begin{tabular}{c} Sample \\ No. \end{tabular} & \begin{tabular}{c} No. \\ Defectives \end{tabular} & \begin{tabular}{c} Sample \\ No. \end{tabular} & \begin{tabular}{c} No. \\ Defectives \end{tabular} & \begin{tabular}{c} Sample \\ No. \end{tabular} & \begin{tabular}{c} No. \\ Defectives \end{tabular} \\ \hline 1 & 7 & 11 & 7 & 21 & 16 \\ 2 & 5 & 12 & 4 & 22 & 11 \\ 3 & 19 & 13 & 17 & 23 & 7 \\ 4 & 11 & 14 & 3 & 24 & 6 \\ 5 & 12 & 15 & 12 & 25 & 12 \\ 6 & 8 & 16 & 9 & 26 & 9 \\ 7 & 12 & 17 & 11 & 27 & 14 \\ 8 & 8 & 18 & 4 & 28 & 5 \\ 9 & 5 & 19 & 17 & 29 & 12 \\ 10 & 13 & 20 & 16 & 30 & 4 \\ \hline \end{tabular} a) Establish 3 upper and lower control limits. UCLp=(enteryourresponseasanumberbetwean0and1,roundedtothreedecimalplaces).LCLp=(enteryourresponseasanumberbetween0and1,roundodtothreedecimalplaces). b) Why can the lower control limit not be a negative number? A. Since the upper control limit cannot be a negative number. B. Since the upper control limit is pasitive. C. Since the percent of defective records is always a positive numbet. D. Since the percent of defective records cannot be a negative number. c) The industry standard for the upper control limit is 0.10. What does this imply about Birmingham Bank's own standards? The industry standard is the standard at Birmingham Bank
