Question:
Consider a hospital for which XRay = 56,194, BedDays = 14,077.88, and LengthStay = 6.89. A 95 percent prediction interval for the labor hours corresponding to this combination of values of the independent variables is given in the following MegaStat output:
95% Confidence Interval | 95% Prediction Interval | |||||
Predicted | lower | upper | lower | upper | Leverage | |
15,925.1659 | 15,369.0460 | 16,481.2857 | 14,876.6586 | 16,973.6731 | 0.3914 | |
Find and report the prediction interval on the output. Then, use this interval to determine if the actual number of labor hours used by the hospital (y= 18,843.64) is unusually low or high.(Report 95% P.I. values to 4 decimal place andyto 2 decimal places.)
