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 ANOVA Regression Residual (Error) 16 1464.98 91.56 Total df 3 3201.82 1067.27 11.66 .000:3 SS MS Significance F 686 19 4666.80 Coefficients Standard Error t-Stat P-Value Intercept 101.92 1.1400 0.3521 0.0935 0.2554 0.0744 0.3108 4.463 4.367 0.301 .0004 .0005 .7674 2 The result of conducting the hypothesis test described in the previous question at the 5% level of significance iS 0005.05, Accept Ho, Relationship is not significant. OR .0005

Explanation / Answer

Q1) Yes,option B is Correct

Q2) multiple Coefficient of determination is 0.686 ( Given in table)

Q3) 68.6% of the variation in y is explained by the regression relationship

Q4) option D as P value of X3 is 0.7674>0.05, so relationship is not significant

Q5) Option D is Correct
