Z-Test Discussion

For this activity, utilize the five-stepprocess and the following data set.

The two populations are:

  • 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.
