Use the following information when answering questions 8) -> 10) below. A doctor is studying the relationship between Systolic blood pressure (Y) and age (X). The doctor takes the blood pressures of 5 randomly- selected HMO patients within each of 4 age classifications. The data appear in the table to the right (Patient Age worksheet). To assess the relationship between blood pressure and age, the doctor fits a one-way ANOVA model and obtains the excel output to the right.
