Exam-style question
Try this first
A test statistic is not in the critical region at the 5% significance level. State the conclusion.
- A.do not reject H0
- B.2o
- C.1o^2
- D.1o
Model answer
What a good answer should say
- The correct answer is do not reject H0.
This answer is tied to the objective: O2 Conduct a statistical hypothesis test for the proportion in the binomial distribution and interpret results in context; understand that a sample is used to make an inference about the population and that the significance level is the probability of incorrectly rejecting the null hypothesis..
Explanation
Why this works
Use the explanation to connect the worked answer back to O2 Conduct a statistical hypothesis test for the proportion in the binomial distribution and interpret results in context; understand that a sample is used to make an inference about the population and that the significance level is the probability of incorrectly rejecting the null hypothesis..
The distractors change the result or the form of the answer. The canonical solution reaches do not reject H0, so do not reject H0 is the only option consistent with the working.
