Multiple Regression Equation
See the attached file.
PG 2 -6
The US Navy selected 16 hospitals that were believed to be efficiently run. They conducted a regression analysis to evaluate the performance of the hospitals in terms of how many labor hours used relative to how many labor hours needed.
Y= monthly labor hours required
X1= monthly X-ray exposures
X2= monthly occupied bed days
X3= average length of patience stay(in days)
Refer to table 11C
A) Determine the multiple regression equation
B) What conclusions are possible using the grobal usefulness test (F-Test)
C) What conclusiona are possible using the T-test of the independent variable (alpha =.05)
D) Using the table, predict the monthly labor hours required when X-ray exposures are 56,194 and the bed days are 14,077.88, and the average length of patient stay is 6.89
