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?
