Question
Consider a questionable 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 on the following MegaStat output:
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 questionable hospital (y = 18,919.22) is unusually low or high. (Report 95% P.I. values to 4 decimal place and y to 2 decimal places.)

From output
95% PI:[15048.7337,16806.2294]
y=18919.22 above the upper limit of the interval.this y value is unusually high
