SYSTOLIC BLOOD PRESSURE IN DIFFERENT AGE GROUPS
The following table contains a random sample of 40 women
partitioned into three groups:
Group 1: ages below 20
Group 2: ages 20 through 40
Group 3: ages over 40
The values in the table are the systolic blood pressure
levels

H0:u1=u2=u3
H1: at least one of the treatment means is different

Exercise 36
The researchers found a significant difference between the
two groups (control and treatment) for change in mobility of the women with
osteoarthritis (OA) over 12 weeks with the results of F(1, 22) 9.619, p 0.005.
Discuss each aspect of these results.
State the null hypothesis for the Baird and Sands (2004)
study that focuses on the effect of the GI with PMR treatment on patients’
mobility level. Should the null hypothesis be rejected for the difference
between the two groups in change in mobility scores over 12 weeks? Provide a
rationale for your answer.
The researchers stated that the participants in the
intervention group reported a reduction in mobility difficulty at week 12. Was
this result statistically significant, and if so at what probability?
If the researchers had set the level of significance or =
0.01, would the results of p 0.001 still be statistically significant? Provide
a rationale for your answer.
If F(3, 60) 4.13, p 0.04, and = 0.01, is the result
statistically significant? Provide a rationale for your answer. Would the null
hypothesis be accepted or rejected?
Can ANOVA be used to test proposed relationships or
predicted correlations between variables in a single group? Provide a rationale
for your answer.
If a study had a result of F(2, 147) 4.56, p 0.003, how many
groups were in the study, and what was the sample size?
The researchers state that the sample for their study was 28
women with a diagnosis of OA, and that 18 were randomly assigned to the
intervention group and 10 were randomly assigned to the control group. Discuss
the study strengths and/or weaknesses in this statement.
In your opinion, have the researchers established that
guided imagery (GI) with progressive muscle relaxation (PMR) reduces pain and
decreases mobility difficulties in women with OA?
The researchers stated that this was a 12week longitudinal,
randomized clinical trial pilot study with 28 women over 65 years of age with
the diagnosis of OA. What are some of the possible problems or limitations that
might occur with this type of study?
