Complete the table 2. Use the table in 1) to find the coefficient of correlation between the variables age of men (X) and their systolic blood pressure (Y). 3. Find the coefficient of determination. r2 = (10(68024) -(415*1511))2 (10*20333-415squared) (10*239415-1511squared) = 0.818744 4. Interpret the coefficient of determination. R2 is 81.874% of systolic bp is justified by age. 5. Find the coefficient of alienation. =1-r2 =1-0.818744 =0.181256 6. Interpret the coefficient of alienation. =0.181256% of the systolic bp is not justified by age
