Using electronic medical records at a large research hospital, 500 patients diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) are matched to 500 patients who do not have MRSA based on sex, age, and reason for admission. Researchers assess length of stay in the hospital and intensive care unit (ICU) admission for possible association to MRSA. 1. Identify the study design (2 pts.) 2. Justify your choice (4 pts.) 3. Determine the appropriate measure of association (2 pts.)

6. Avogadro's number can also be calculated from this experiment. (a) Calculate the number of electrons that were lost from the total Coulombs and the fact that the charge on an electron is 1.602 x $10^{-19}$ Coulombs. Total # of Coulombs = 37.33 (b) Two electrons are lost for each atom of Cu, so the number of Cu atoms is (c) This number of atoms corresponds to the measured mass of Cu lost. If 63.54 grams of copper (one mole) is lost, how many atoms of Cu would be lost? (d) The accepted value for Avogadro's number is 6.02 x $10^{23}$. Calculate the percent error in your determination of Avogadro's number.
