bA 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, she inspected $1,000$ units of output from each machine in random samples, with the following results:

Machine

Total Defectives

#$1$

$23$

#$2$

$15$

#$3$

$29$

#$4$

$13$

For upper and lower control limits of $\mathrm{.}026$ and $\mathrm{.}014,$ which machine$($s$),$ if any, appear$($s$)$ to be out$-$of$-$control for process proportion of defectives?
