Homework Answers
Answer. Option. e. both an x-bar chart and an R-chart
For such cases, x bar and r chart are appropriate because they provide us the mean of the data and variability of the process from the desired goal and help us in assigning the causes for this variability.
P chart or c chart is inappropriate in this case because we are not concerned about defects or defectives here.

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
