A manager has to develop a control chart for determining whether three homogenous processes are in control. Accordingly, she sampled four units of output from each process, with the following results: Process $1-17,15,15,17$; Process $2-16,25,18,25$; Process $3-23,24,23,22.$ For upper and lower control limits of $23\mathrm{.}29$ and $16\mathrm{.}71,$ which process$($s$),$ if any, appear$($s$)$ to have an out$-$of$-$control process mean?
