Question: Using these t values test each independent variable separately; i.e. test
Ho: B1 = 0 vs. Ha: B1 not equal to 0 AND Ho: B2 = 0 vs Ha: B2 not equal to 0 AND
Ho: B3 = 0 vs. Ha: B3 not equal to 0. Let alpha =.05.
y = monthly labor hours required
X1 = monthly x-ray exposures
X2 = monthly occupied bed days
X3 = average length of patient stay ( in days)
