There are two populations:

  • Population A:
    • Mean=36, SD=4
  • Population B:
    • (sample of one): Raw Score=44

Set up a one-tail Z test evaluating the improvement of a score, presenting the following:

  1. Restate the research question as a research hypothesis and a null hypothesis about the populations.
  2. Determine the characteristics of the comparison distribution.
  3. Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected.
  4. Determine your sample's score on the comparison distribution.
  5. Decide whether to reject the null hypothesis.
