Question

A major health care organization conducted a study relating the risk of heart attack to a patient's age, blood pressure, and HDL cholesterol. They have hypothesized the following relationship where Y is heart attack risk, Xj is patient's age, X2 is blood pressure, and X3 is HDL level. Data are collected and a regression relationship is determined through the use of the computer. The following Excel output is obtained Regression Statistics Multiple R 828 R Square Standard Error 9.57 Observations 20 df 3 3201.82 1067.27 11.66 .0003 ANOVA Regression Residual (Error) 16 1464.98 91.56 Total SS MS Significance F 686 19 4666.80 Coefficients 101.92 Standard Error t-Stat P-Value Intercept 4.463 4.367 0.301 The value of the sample multiple coefficient of determination is 1.1400 0.3521 0.0935 0.2554 0.0744 0.3108 .0004 .0005 .7674 2 A 0.828 B. 9.57 C.0.686 D.91.56

Explanation / Answer

Solution :--

Multiple R is the coefficient of multiple correlation,

and R square is the Multiple Coefficient of determination.

From the above output ,

The Sample Multiple Coefficient of Determination = R Square

= 0.686
