  1. Please calculate using SPSS whenever possible. 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. 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?
  2. Give a 95% CI around the predicted slope coefficient and interpret.
  3. Using the prediction equation, what is the predicted systolic blood pressure for a
    1. 44 year old?
    2. 61 year old?
    3. 70 year old?
  4. Which of the above predictions should not be trusted? Why?

Research Scenario Hypertension is defined as a systolic blood pressure (SBP) of 140 mmHg or more, or a diastolic blood pressure (DBP) of 90 mmHg or more. Diastolic blood pressure (DBP) measurements from the general population form a normal distribution with m = 82 mmHg and s = 10 mmHg. Epidemiological studies have shown that obesity increases the risk of hypertension (high DBP). Using data from a cohort study, a researcher obtained a sample of n = 144 obese persons...
