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?

  1. Use the 5 steps of hypothesis testing
  2. Sketch the distribution with cut-off value(s) and sample t-score, and regions of acceptance and rejection labeled.
  3. Summarize what you found.

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...
