Question $1.$ Control Chart Basics $($with population information$).$A high$-$voltage power supply should have a nominal output voltage of $350$ V$.$ The population meanand 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 datashown below demonstrates each units nominal voltage for six days.Q$1-4.$ Using the given population information, set up the R chart $($Chart #$2).$ Indeed, calculateCL, UCL, and LCL$.$
