Larry's boat shop wants to monitor the number of blemishes in the paint of each boat. Construct a $3-$sigma control chart to deter if their paint process is in control using the following data.

$\backslash$table$[[$Boat$,\backslash$table$[[$Number of$],[$Defects$]]],[1,3],[2,4],[3,2],[4,5],[5,2],[6,3],[7,2],[8,4],[9,3],[10,3]]$

Using $+-3$ limits$,$ calculate the LCL and UCL for the above data.

A$)$ UCL$=7\mathrm{.}437$;$LCL=-2\mathrm{.}237$

B$)$ UCL$=8\mathrm{.}382$;$LCL=-2\mathrm{.}182$

C$)$ UCL$=7\mathrm{.}437$;$LCL=0$

D$)$ UCL$=8\mathrm{.}382$;$LCL=0$

E$)$ UCL$=9\mathrm{.}112$;$LCL=0$
