2. List and explain the logic of the five hypothesis testing steps. Step 3 of hypothesis testing is ______________.
3. List and explain the logic of the five hypothesis testing steps. Step 5 of hypothesis testing is ______________.

Objective: Apply techniques Conducting a hypothesis test

4. In a study, researchers want to compare task performance of participants who see images related to ambiguous partial word stimuli presented later, to other participants who see images that are unrelated. The number of words completed in the task is recorded to see if there is a difference. Data: Normative neuropsychological data have established that the mean words completed by the population of people who have seen unrelated images is 5, with standard deviation 2.4. The individual in this study who saw related images completed 9 words. In this hypothesis test, the two populations are ______________.
5. In a study, researchers want to compare task performance of participants who see images related to ambiguous partial word stimuli presented later, to other participants who see images that are unrelated. The number of words completed in the task is recorded to see if there is a difference. Data: Normative neuropsychological data have established that the mean words completed by the population of people who have seen unrelated images is 5, with standard deviation 2.4. The individual in this study who saw related images completed 9 words. In this hypothesis test, the hypotheses are ______________.
6. In a study, researchers want to compare task performance of participants who see images related to ambiguous partial word stimuli presented later, to other participants who see images that are unrelated. The number of words completed in the task is recorded to see if there is a difference. Data: Normative neuropsychological data have established that the mean words completed by the population of people who have seen unrelated images is 5, with standard deviation 2.4. The individual in this study who saw related images completed 9 words. In this hypothesis test, Step 2 characteristics of the comparison distribution would be ______________.
7. In a study, researchers want to compare task performance of participants who see images related to ambiguous partial word stimuli presented later, to other participants who see images that are unrelated. The number of words completed in the task is recorded to see if there is a difference. Data: Normative neuropsychological data have established that the mean words completed by the population of people who have seen unrelated images is 5, with standard deviation 2.4. The individual in this study who saw related images completed 9 words. In this hypothesis test, assuming a significance level of .01, the cutoff score(s) in Step 3 is/are ______________.
8. In a study, researchers want to compare task performance of participants who see images related to ambiguous partial word stimuli presented later, to other participants who see images that are unrelated. The number of words completed in the task is recorded to see if there is a difference. Data: Normative neuropsychological data have established that the mean words completed by the population of people who have seen unrelated images is 5, with standard deviation 2.4. The individual in this study who saw related images completed 9 words. In this hypothesis test, Step 4 would give the Z-score result of ______________.
9. In a study, researchers want to compare task performance of participants who see images related to ambiguous partial word stimuli presented later, to other participants who see images that are unrelated. The number of words completed in the task is recorded to see if there is a difference. Data: Normative neuropsychological data have established that the mean words completed by the population of people who have seen unrelated images is 5, with standard deviation 2.4. The individual in this study who saw related images completed 9 words. In this hypothesis test, the conclusion in Step 5 should be ______________.
