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 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.

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...

To determine whether high blood pressure affected whether a
person had a stroke, a sample of 121 people who had had strokes are
examined. In the sample, 40% had high blood pressure. If we were to
test the hypothesis that at least 33% of the people who have had
strokes have had high blood pressure (using the 10% level of
signficance) what is the critical value? (please round your answer
to 2 decimal places)

A researcher conducted a study to whether age, gender, obesity,
high blood pressure and regular physical activity is associated
with the risk of recurrent MI (measured as serum cholesterol level)
in post MI patients. A sample of 60 people was obtained from the
community. All subjects had their serum cholesterol level
drawn.
Research question: Do age, gender, obesity, high blood pressure and
regular physical activity predict the serum cholesterol level?
Please indicate which statistical test should be
used.

2. A researcher wishes to determine whether there is a
difference in the average age of elementary school, high school,
and community college teachers. Teachers are randomly selected from
each group. Their ages are recorded below. Test the claim that at
least one mean is different from the others. Use α = 0.01.
Resource: The One-Way ANOVA
Identify the null hypothesis, Ho, and the alternative
hypothesis, Ha.
Determine whether the hypothesis test is left-tailed,
right-tailed, or two-tailed.
Find the critical...

Dentists make many people nervous. To see whether such
nervousness elevates blood pressure, the blood pressure and pulse
rates of 60 subjects were measured in a dental setting and in a
medical setting. For each subject, the difference (dental-setting
blood pressure minus medical-setting blood pressure) was
calculated. The analogous differences were also calculated for
pulse rates. Summary data are given below.

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
