Homework Answers
Solution:
We have to study the effect of new Drug A to treat type 2 diabetes Vs the standard of care in a randomized controlled trial.
Sample size of 1000 is divided in to two samples
500 for Drug A and 500 for the standard of care.
Thus we have two independent samples: Drug A and the standard of
care.
Since we have two independent samples, we use
Independent T-test to test if there is difference
between mean glucose level of Drug A and the standard of care.
Add Answer to:
Which test is correct?

Problem 3 Weight reduction is an important goal for the management of type 2 diabetes (T2D) among overweight patients. A 2016 study evaluated the effect of oat intake (a cereal grain) for overweight T2D patients. A total of 298 overweight T2D subjects (BMI of at least 24 kg/m2) were randomly assigned to follow one of 4 dietary guidelines for 30 days, as shown in the diagram below. The two “oats” groups ate the same healthy diet as the “diet" group,...

In a study of 380 diabetics and nondiabetics, patients were classified as underweight, normal weight, overweight and obese according to their diabetes status. The probability of being normal weight is 0.31 and the probability of having diabetes is 0.39. If you select two individuals from the population, the probability of being diabetic and normal weight is 0.09. What is the probability that either of the two randomly selected individuals (or both) will be diabetic or normal weight? a. Pr (diabetic...

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...
