$1.$ A Quality Analyst wants to construct a control chart for determining whether four machines, all producing the same product, are under control with regard to a particular quality attribute. Accordingly, the analyst inspected $1,000$ units of output from each machine in random samples, with the following results:

Machine

Total Defectives

#$1$

$23$

#$2$

$15$

#$3$

$29$

#$4$

$13$

If upper and lower control limits were set as $0\mathrm{.}028$ and $0\mathrm{.}010,$ which machine$($s$),$ if any, appears$)$ to be out$-$of$-$control for process proportion of defectives?

Machines #$2$ and #$3$

Machine #$3$ only

Machines #$3$ and #$4$

Machine #$4$ only
