Correct option is (E) Independent T-test (You have answered correctly)
Here both the samples(500 each) are independent to each other and their effectiveness will be measured in terms of mean glucose level and on the basis of the glucose level with the help help of corresponding sample mean and standard deviation we would be able to make final conclusion for the effectiveness.

2. Researchers are evaluating a new drug for the treatment of Type II diabetes. They ran- domly assign 20 volunteers with a history of poor glucose control levels to two groups the Treatment group gets the experimental drug on trial, while the Control group re- ceives a standard drug. At the end of the clinical trial, participants have their A1C (glycated hemoglobin, a measure of long-term blood glucose levels) tested, the results are summarized in the table below Group A1C...

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...

E. Longitudinal study 12. A researcher is examining the effectiveness of a new drug on serum blood glucose in an anmal model of diabetes. He gives 20 rats a single dose every day for 1 week and gives a similarly matched group of 20 rats a daily placebo dose over the same 1-week period. Following the final dose administration, the investigator measures the blood glucose level in the rats, using a value of 120g/dL as a cutoff do define hyperglycemia....
