Three patients have made appointments to have their blood pressure checked at a clinic. As each patient is selected, he/she is tested. If he/she has high blood pressure, a success (S) occurs; if he/she does not have high blood pressure, a failure (F) occurs. Let x be the number of persons who have high blood pressure (i.e., Let x represent the number of successes among the three sampled persons).
a. How many outcomes should you have from this probability experiment?
b. Construct a tree diagram for the number of persons who have high blood pressure.
c. List all outcomes from this probability experiment.
d. What are the possible values for x?
e. Construct the probability distribution of x.
f. Determine whether the table represents a discrete probability distribution. Explain
g. Find P(x=1)=
h. Find P( x ≤ 2)=
i. Find P(x >2)=
j. Find P (x ≥ 2)=
k. Find (x=0)=
l. Compute the mean,
m. Compute the variance,
n. Compute the standard deviation,

Four patients have made appointments
to have their blood pressure checked at a clinic. As each patient
is selected, he/she is tested. If he/she has high blood pressure, a
success (S) occurs; if he/she does not have high blood pressure, a
failure (F) occurs. Let x be the number of persons who have high
blood pressure (i.e., Let x represent the number of successes among
the four sampled persons).

In a clinic, a random sample of 60 patients is obtained, and
each person’s red blood cell
count (in cells per microliter) is measured. The sample mean is
5.28. The population
standard deviation for red blood cell counts is 0.54.
(a) At the 0.01 level of significance, test the claim that the
sample is from a population
with a mean less than 5.4. [4 marks]

A nurse measured the blood pressure of each person who visited her clinic.
A nurse measured the blood pressure of each person who visited her clinic. Following is a relative-frequency histogram for the systolic blood pressure readings for those people aged between 25 and 40. The blood pressure readings were given to the nearest whole number. Approximately what percentage of the people aged 25-40 had a systolic blood pressure reading between 110 and 119 inclusive?

A medical researcher wishes to try three different techniques to
lower the blood pressure of patients with high blood pressure. The
subjects are randomly selected and assigned to one of three groups.
Group 1 is given medication, Group 2 is given an exercise program,
and Group 3 is assigned a diet program. At the end of six weeks,
each subject's blood pressure is recorded
