A study of the effects of color on easing anxiety compared anxiety test scores of participants who completed the test printed on either soft yellow paper or harsh green paper. The researcher predicted that the yellow paper would produce lower anxiety scores than the green paper.
The scores for the six participants who completed the test printed on the yellow paper were: 17, 19, 28, 21, 18, 20.
The scores for the five participants who completed the test of the green paper were 20, 26, 17, 24, 21.
Using the .05 significance level, and selecting an appropriate test (one or two tailed), what should the researcher conclude? Should they accept or reject the null hypothesis?
- Use the 5 steps of hypothesis testing
- Sketch the distribution with cut-off value(s) and sample t-score, and regions of acceptance and rejection labeled.
- Summarize what you found.

Design a Study to Test one of the following:
Scenario 3: Anxiety and depression play a role in the speed and
quality of recovery from illness. Past research indicates that
owning and caring for a pet may counter symptoms of anxiety and
depression. There are numerous types of therapy available to ill
patients but is owning a pet also a viable treatment for relieving
anxious and depressive symptoms?
Clearly identify the scenario you chose. In your
response, clearly identify your...

Participants enter a research study with unique characteristics
that produce different scores from one person to another. For an
independent-measures study, these individual differences can cause

A study that evaluated the effects of a reduction in exposure to
traffic-related air pollutants compared respiratory symptoms of 281
residents of an area with congested streets with 168 residents in a
similar area where the congestion was removed because a bypass was
constructed. The symptoms of the residents were evaluated at
baseline and again a year after the bypass was completed. For the
residents of the congested streets, 16 reported that their symptoms
of wheezing improved between baseline and...
