Answer
First, subtract the generic drug data from the reference drug data. The null for this problem is H: u = 0 and the alternative is H: u$\ne$0. The t statistic is $\frac{-37 - 0}{1070.62/\sqrt 20}$ = -.155 hence a p-value of .88. Therefore, there is no strong evidence that the drugs differ in absorption.
