7. You are a RN working in the cardiac outpatient clinic of a large teaching hospital. You are interested in the predictors of high blood pressure in cardiac patients. You have access to a data set of 1,267 clinic patients that contains data on age (AGE, years), sex (MALE, 1=Yes, 2=No), dystolic blood pressure (DBP, mmHg ), systolic blood pressure (SBP, mmHg) and body mass index (BMI). Previous research has shown that DBP and SBP are approximately normally distributed. The excel data set containing the data on these patients is available in the 'Data Sets' folder under the Contents tab in A2L. The data set is called DBP_SBP.xIsx. Use these data to answer the questions below. a. Run a simple linear regression in SPSS to predict DBP from BMI. Using two measures from the SPSS output, comment on whether BMI is useful in predicting DBP. Provide the output to support your comments. [2 Marks] b. Run a simple linear regression in SPSS to predict SBP from AGE. Using two measure from the SPSS output, comment on whether AGE is useful in predicting SBP. Provide the output to support your comments. [2 Marks] c. Generate an appropriate plot showing the relationship between DBP and BMI. Comment on the pattern seen in this plot in relation to the results you obtained in question (a) above. [1 Mark]
