Question: Answer each of the following question. No explanation is needed- just short answer.)

  1. You are reading an article in your field that reports several statistical analyses. The article says that the P- value for a significance test is 0.045 . Is the result significant at the 5% significance level?
  2. Is the result with P-value 0.045 significant at the 1% significance level?
  3. For another significance test, the article says only that the result was significant at the 1% level. Are such results always, sometimes, or never significant at the 5% level?
  4. Reaction times of a subject to a stimulus are often strongly skewed to the right because of a few slow reaction times. You wish to test:

    Where is the mean reaction time for Stimulus 1, for stimulus 2. You have two independent samples, eight observations for stimulus 1 and ten for stimulus 2. Which, if any, of the test you have studied can be used to test this?
  5. The article contains a 95% confidence interval. Would the margin of error in a 99% confidence interval computed from the same data be less, the same, or greater?
