study was conducted examining two different drugs (n=12,000). Both drugs are known for lowering blood cholesterol levels. Drug A outperformed Drug B and the 95% confidence interval estimate of the difference in mean cholesterol level lowering was (18, 41). Which of the following is a reasonable conclusion?
|
There is a 0.95 probability that Drug A will outperform Drug B by at least 23 points in lowering the cholesterol level of any given individual. |

|
There is a 0.95 probability that Drug A will outperform Drug B in lowering the cholesterol level of any given individual. |
||
|
None of the other explanations are correct. |
||
|
We should be 95% confident that Drug A will outperform Drug B as a cholesterol-lowering drug. |
Homework Answers
Drug A outperformed Drug B and the 95% confidence interval estimate of the difference in mean cholesterol level lowering was (18, 41).
So the correct option is We should be 95% confident that Drug A will outperform Drug B as a cholesterol-lowering drug.

1. In a test to compare the effectiveness of two drugs designed to lower cholesterol levels, 75 randomly selected patients were given drug A and 100 randomly selected patients were given drug B. Those given drug A reduced their cholesterol levels by an average of 41 with a standard deviation of 12, and those given drug B reduced their levels by an average of 42 with a standard deviation of 16. The units are milligrams of cholesterol per deciliter of...

Antipsychotic drugs are widely prescribed for conditions such as schizophrenia and bipolar disease. An article reported on body composition and metabolic changes for individuals who had taken various antipsychotic drugs for short periods of time. (a) The sample of 41 individuals who had taken aripiprazole had a mean change in total cholesterol (mg/dL) of 3.45, and the estimated standard error – - was 3.278.

Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
