A5. Suppose that a researcher regressed surgical patients’ length of stay in hospital (Y ) on a scale of functional ability measured 24 hours after surgery (X). Given the following, solve for the value of the intercept constant and write out the full regression equation: Mean length of stay = 6.5 days; mean score on scale = 33.0; slope = -.10.
