Question $4[15$ Points$]$: A physician practice specializing in managing spine pathology is assessing the feasibility of adding a C$-$arm imaging unit. Implementation of C$-$arm procedures would require hiring one or more radiology technicians to assist the physician. The practice manager, being familiar with forecasting techniques, has already developed a projection of annual C$-$arm procedures, and would like to determine the target level of radiology FTEs should the C$-$arm imaging unit be added

at the practice. The table below outlines the forecasted volume of each procedure over an eightmonth period and estimated standard hours per procedure performed by a radiology technician. Indirect support time is $0\mathrm{.}15$ hours per procedure, and constant time by all staff is two hours per day. The fringe benefit allowance is $10\%$ and the practice utilization target is $85\%.$
