Capital punishment law is among the most complex bodies of law in the US. As a result of frequent errors, the Trial Judges Assn. has developed a special training course to try to cut down on the errors.
To study whether the training is effective, you perform a hypothesis test. What are the null and research hypotheses? Describe type 1 and type 2 errors in this case.© BrainMass Inc. brainmass.com March 4, 2021, 11:05 pm ad1c9bdddf
To examine if the training is effective, you may conduct either a two-tailed or a one-tailed hypothesis test. I will provide the null and research hypotheses and Type 1 and Type 2 errors for both two-tailed and one-tailed hypothesis testing situations.
Two-tailed hypothesis testing:
Null hypothesis: In the population, there is no difference between the number of errors before and after the training.
Solution includes the appropriate null and research hypotheses with the descriptions of Type 1 and Type 2 errors.
