QUESTION $50$

A quality analyst wants to construct a control chart for determining whether four machines, all producing the same product, are in control with regard to a particular quality attribute. Accordingly, sh each machine in random samples, with the following results:

$\backslash$table$[[,$Total Defectives$],[$Machine$,23],[$#$1,15],[$#$3,29],[$#$4,13]]$

What is the control chart upper control limit for an alpha risk of $)=(1\mathrm{.}96?$

The upper control limit is less than or equal to $0\mathrm{.}024$

The upper control limit is greater than $0\mathrm{.}024$ but less than or equal to $0\mathrm{.}03$

The upper control limit is greater than $0\mathrm{.}03$ but less than or equal to $0\mathrm{.}036$

The upper control limit is greater than $0\mathrm{.}036$ but less than or equal to $0\mathrm{.}042$

The upper control limit is greater than $0\mathrm{.}042$
