randomly selected applications.

What are the upper and lower control limits of a $p-$chart for the number of defective applications? Use $z=3.$

$"$P$-$bar$=0\mathrm{.}2028,$ UCL$=0\mathrm{.}2673,$ LCL$=0\mathrm{.}1384"$

$"$P$-$bar$=0\mathrm{.}1028,$ UCL$=0\mathrm{.}1673,$ LCL$=0\mathrm{.}0384"$

$"$P$-$bar $=0\mathrm{.}0528,$ UCL $=0\mathrm{.}1173,$ LCL $=0\mathrm{.}00$

$"$P$-$bar$=0\mathrm{.}2528,$ UCL$=0\mathrm{.}3173,$ LCL$=018384"$

Are there any samples out of control?
