- A researcher wishes to determine whether the systolic blood pressure of people who follow a vegetarian diet is, on average, lower than the systolic blood pressure of those who do not follow a vegetarian diet. Independent simple random samples of 85 vegetarian and 75 nonvegetarians yielded the following sample statistics:
|
Vegetarians |
Nonvegetarians |
|
Mean = 124.1 |
Mean = 138.7 |
|
s1 = 38.7 |
s2 = 39.2 |
Use the significance level of 0.01 to test the claim of the researcher.

TWO MEANS
A researcher wishes to determine whether people with high blood
pressure can reduce their blood pressure by following a particular
diet. Use the sample data below to test the claim that those who
followed the diet have a lower mean blood pressure than those who
did not followed the diet.
Followed the diet: n1 = 85, x ̅_1 = 189.1 s1 = 38.7 Did not
follow the diet: n2 = 75, x ̅_2 = 203.7 s2 = 39.2...

A researcher wishes to determine whether the blood pressure of
vegetarians is, on average, lower than the blood pressure of
nonvegetarians. Independent simple random samples of 85 vegetarians
and 75 nonvegetarians yielded the following sample statistics for
systolic blood pressure:
Vegetarians
n1= 85
= 124.1 mmHg
s1 = 38.7 mmHg
Nonvegetarians
n2 = 75
= 138.7 mmHg
s2 = 39.2 mmHg
Use a significance level of 0.01 and P-value method to test the
claim that the mean systolic blood pressure...

According to the WHO MONICA Project the mean systolic blood
pressure for people in China is 128 mmHg with a standard deviation
of 23 mmHg (Kuulasmaa, Hense & Tolonen, 1998). Systolic blood
pressure is normally distributed. a.) TRUE or FALSE: The random
variable is defined as systolic blood pressure of a person in
China. b.) For a sample of size 15, state the mean of the sample
mean. c.) For a sample of size 15, state the standard deviation of...

A medical researcher is investigating the effect of drinking
coffee on systolic blood pressure. The researcher assumes the
average systolic blood pressure is 120 mmHg. For a random sample of
200 patients, the researcher takes two measurements of systolic
blood pressure. The first systolic blood pressure measurement is
taken during a week when the patients drink no coffee, and the
second systolic blood pressure measurement is taken during a week
when the patients drink at least two cups of coffee....

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 22.8 millimeters of mercury. The wellness department
of a large corporation is investigating if the mean systolic blood
pressure is different from the national mean. A random sample of
200 employees in a company were selected and found to have an
average systolic blood pressure of 124.7 mmHg.

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.
The wellness department of a large corporation is investigating
whether the mean systolic blood pressure of its employees is
greater than the reported national mean. A random sample of 50
employees will be selected,...

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...

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. Using this data, find the 99% confidence interval for the
true difference in blood pressure for each patient after taking the
new drug. Assume that the blood pressures are normally distributed
for the population of patients both before and...
