A group of researchers is studying how treatments may affect Alzheimer’s patients’ ability to remember daily tasks. In this study, 30 Alzheimer’s patients were taught a set of words using the visual cues, and another group of 30 Alzheimer’s patients was taught the same set of words using both visual cues and intense verbal rehearsal. Both groups were quizzed on their memory of the word sets 1 hour after the instruction phase. The number of words correctly recalled by each patient was recorded and comprises the data. Use the data file, Alzheimer's Study.csv as needed to answer the following: a. State the hypotheses for this hypothesis test. b. Do the data meet all th

Use the data file, Alzheimer's Study.csv as needed to answer the following:
a. State the hypotheses for this hypothesis test.
b. Do the data meet all the assumptions of the appropriate hypothesis test? Why or why not? (please include screenshots of the relevant part of the jamovi output to support your answers)
c. Conduct the appropriate hypothesis test in jamovi and include a screenshot of the main analysis table from jamovi
d. Make a decision about the null hypothesis using α = .05. Why did you make this decision?
e. What does this decision suggest about the effectiveness of the two approaches for memory performance in Alzheimer’s patients?
f. Write up the results of this hypothesis test, relating your decision back to the research question. Be sure to include all elements of the write-up that are required as per class examples.
