  1. We have age and systolic blood pressure (SBP) of 10 randomly chosen people. Using this data, we would like to create a model to predict systolic blood pressure from age.

  1. (2pts) Obtain the R2 value and interpret.
  2. (4pts) What is the overall test statistic from the ANOVA table? What is the test statistic for the slope coefficient? Are they equal or not equal? Why is this the case?

Please show SPSS Commands, if possible. Thank you!

Answer #1

Above problem is solved using SPSS



a.

R2 = 0.867

The amount of variation in SBP explained by Age is 0.867

b.

Overall test statistics = 52.275

Test statistics for slope coefficient is 7.230

They both qre different because the overall test statistics measures the overall significance of the model and test statistics for slope coefficient is used to measure the significance of Independent variable.

The data (bloodpressure) (first column is ID) gives the systolic blood pressure (SBP), body size (QUET), age and smoking history (SMK=0 if nonsmoker, SMK=1 if smoker) for a hypothetical sample of 32 white males over 40 years old from the town of Angina. In the problem, we will choose SBP as the response. The two variables QUET and SMK will be considered. Answer the following questions about the separate straight-line regression of SBP on QUET for smokers (SMK=1) and nonsmoker...

A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Data from a portion of this study are contained in the Excel Online file below. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker. Construct a spreadsheet to answer the following questions....

I have two devices to check my blood pressure; one checks it at the wrist, and the other just above the elbow. I want to see if there is any difference in the two machines, so I check my blood pressure with both devices at the same time one morning. On the next five mornings, i repeat this check with both machines. The following table show the systolic reading at the elbow and wrist for these six days: elbow 134...
