The following data reflect information from 17 U.S. Naval hospitals at various sites around the world. The regressors are workload variables, that is, items that result in the need for personnel in a hospital. A brief description of the variables is as follows: y monthly labor-hours, = x1 average daily patient load, = x2 monthly X-ray exposures, x3 = monthly occupied bed-days, x4 = eligible population in the area/1000, x5 = average length of patient's stay, in days.

Estimate the multiple linear regression equation and interpret all the results from the MINITAR.
