Question
A simple linear regression model was created to examine the relationship between the age of patients in years (i.e. the independent variable) and the patients' scores on a questionnaire that measures quality of life (i.e. the dependent variable). There were n=20 patients in the study, and some of the results of the regression are presented below:
Estimated slope = -0.64
Standard error of the slope = 0.52
Estimated intercept = 42.0
Standard error of the intercept = 13.6
Based on these results, what would be the expected quality of life score for a patient who is 30 years old?
