Question

2) During heart transplant surgery, an inflammation marker has these parameters: μ = 3.0 pg/ml and σ = 2.0 pg/ml. A new drug tested on 10 men undergoing transplants gives a mean of 2.0 pg/ml.

A) Did these men have significantly lower inflammatory maker levels at the .05 significance level (α = 0.5)?

B)Assuming the drug actually does lower the marker to 2.0 pg/ml, what was the power of this test?

C)Should the researchers be convinced that this drug does/does not lower inflammation by 1.0 pg/ml? Why?
