A 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?

1.None of the other explanations are correct.

2.There is a 0.95 probability that Drug A will outperform Drug B in lowering the cholesterol level of any given individual.

3.We should be 95% confident that Drug A will outperform Drug B as a cholesterol-lowering drug.

4.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.
