Determine the if there is a *significant (p=0.05)* difference on the frequency of HIV when specimen is 3 ml or greater vs less than 3 ml.

data:
total of 257 samples: 156 specimens are 3ml or greater and 101 specimens are less or equal to 3 ml.
Of the 156 samples (greater or equal to 3ml) only 54 are HIV positive. of the 101 specimens, only 34 samples are HIV positive.

Let denote the proportion of HIV positive among specimens for less than 3 ml and greater than 3 ml.

So, we can conclude that there is significant difference on the frequency of HIV when specimen is 3 ml or greater vs less than 3 ml.

The enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9 mol/l). The dissociation constant of the complex ED2 formed...
