Efficiency of General Hospital. In Section $5\mathrm{.}1$ data envelopment analysis was used to evaluate the relative efficiencies of four hospitals. Data for three input measures and four output measures were provided in Tables $5\mathrm{.}1$ and $5\mathrm{.}2.$ LO $1$ a$.$ Use these data to develop a linear programming model that could be used to evalu$-$ate the performance of General Hospital.$$b$.$ The following solution is optimal. Does the solution indicate that General Hospital is relatively inefficient?$$Variable E$$WG WU WC WS$$Objective Function Value $51\mathrm{.}000$ Value $1\mathrm{.}0001\mathrm{.}0000\mathrm{.}0000\mathrm{.}0000\mathrm{.}000$Reduced Costs $0\mathrm{.}0000\mathrm{.}0000\mathrm{.}0000\mathrm{.}3310\mathrm{.}215$c$.$ Explain which hospital or hospitals make up the composite unit used to evaluate General Hospital and why.
