1)
A patient visits
his doctor with concerns about his blood pressure. If the systolic
blood pressure exceeds 150, the patient is considered to have high
blood pressure and medication may be prescribed.
The
patient’s systolic readings during a given day have a Normal
distribution with a mean of 160 and a standard deviation of
20.
a)
What
is the probability
that a single measurement will be less than 150 and hence fail
to indicate that the patient has a high blood pressure
problem?
b)
If 10 measurements
are taken at various times during the day, what is the probability
that the average blood pressure readings will be less than 150 and
hence fail to indicate that the patient has a high blood pressure
problem?

Expert Solution
We will calculate these probabilities using the areas under
standard normal curve.

A patient visits her doctor with concerns about her blood
pressure. If the systolic blood pressure exceeds 150, the patient
is considered to have high blood pressure and medication may be
prescribed. The problem is that there is a considerable variation
in a patient’s systolic blood pressure readings during a given
day.
A. If a patient’s systolic readings during a
given day have a normal distribution with a mean of 155 and a
standard deviation of 20, what is the...

17. The following results belong to a patient who visited his
cardiologist:
Systolic Blood Pressure: 127
Diastolic Blood Pressure: 99
Heart Rate: 105bpm
Stroke Volume: 0.07L
Answer the following based on the information provided (show
your work and use appropriate units):
What is the patient’s cardiac output in mL/min?
What is the patient’s mean arterial pressure?
Is the patient hypertensive? If so to what degree?
How would you classify the patient’s heart rate?

Systolic blood pressure is the amount of pressure that blood
exerts on blood vessels while the heart is beating. The mean
systolic blood pressure for people in the United States is reported
to be 122 millimeters of mercury (mmHg) with a standard deviation
of 15 mmHg.

A pharmaceutical company claims that its new drug reduces
systolic blood pressure. The systolic blood pressure (in
millimeters of mercury) for nine patients before taking the new
drug and 2 hours after taking the drug are shown in the table
below. Is there enough evidence to support the company's claim? Let
d = (blood pressure before taking new drug) − (blood pressure after
taking new drug). Use a significance level of α = 0.05 for the
test. Assume that the...
