Solutions
Expert Solution
a] The required model for given set of data is
where x is AGE Independent variable
SBP is systolic blood pressure (SBP) dependent variable.
is intercept
slope parameter
b]
SO REQUIRED EQUATION IS
Interpretation: For every an year increase in Age then there will be an increase of 1.966 SBP

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...

A medical researcher wants to begin a clinical trial that
involves systolic blood pressure (SBP) and cadmium (Cd) levels.
However, before starting the study, the researcher wants to confirm
that higher SPB is associated with lower Cd levels. Below are the
SBP and Cd measurements for a sample a participants. What can the
researcher conclude with an α of 0.10?
