Question $1.$ Control Chart Basics $($with population information$).$A high$-$voltage power supply should have a nominal output voltage of $350$ V$.$ The population mean and population standard deviation are known to be $350$ and $0\mathrm{.}7,$ respectively. $(=350,=0\mathrm{.}7).$ A sample of four units is selected each day and tested for process$-$control purposes. The data shown below demonstrates each units nominal voltage for six days.Q$1-1.$ What is the sample size $()?$Q$1-2.$ Using the given population information, set up the X$-$bar chart $($Chart #$1).$ Indeed, calculate CL$,$ UCL, and LCL$.$Q$1-3.$ Complete your X$-$bar chart from Day $1$ to Day $6$ by plotting your daily observations onto the chart.
