Question

Consider the study described in Problem 3. Suppose that we investigate the relationship between age and the severity of arthritis (measured on scale from 0 to 100, with higher scores indicative of more severe diseasc). The following summary statistics are available on the total sample (n = 175): Characteristic Mean Age Severity score 57.7 59.8 The point estimate for the correlation between age and severity score 0.36 (p = 0.0001) . Is there evidence of significant correlation between age and severity score among all patients? Estimate the equation of the line that best describes the relationship between age and severity score (consider severity score as the dependent variable). What is the expected severity score for an individual 60 years of age?
