Question: A hospital administrator wishes to study the relationship between patient satisfaction with his age (measured in years), the severity of the disease treated (measured by an index) and the level of anxiety (measured by an index). The administrator collects information from a random sample of 23 patients presented below.

  1. What kinds of variables are satisfaction, severity, age, and anxiety? Why is it possible to perform a multiple linear regression analysis even though some variables are qualitative?
  2. Estimate the multiple linear regression model and interpret the coefficients.
  3. What is the adjusted coefficient of determination? Is the fit good?
