Quiz 4 This is an example we talked about in class when we learn the bootstrap. You wish to invest a fixed sum of money in two financial instruments that yield returns of $ X $ and $ Y $ (random quantities). You put fraction $ \alpha $ into $ X $ and the rest $ 1-\alpha $ into $ Y $, and you want to minimize the total risk or variance of your investment; that is, $ \min _{\alpha} \alpha X+(1-\alpha) Y $. Can you prove that the optimal $ \alpha $ is the one shown in the lecture slide?

Consider the following analyses of cocaine by two different GC-MS protocols. Is the new protocol providing values that are different than the old protocol (p < 0.05)? Assume that the analyst is the same in each case and that "s" approaches "sigma" (use population statistics rather than sample statistics). All measures are in units of % w/w. Old = 6.32, 6.21, 6.25, 6.38 New = 6.30, 6.44, 6.45, 6.38

3. (1) Ceramics and polymers both have covalent bonds. However, the ultimate tensile strength (UTS) of polymers is rarely higher than 100 MPa, while ceramics can have UTS as high as 1GPa. (2) Each water molecule consists of two hydrogen atoms and one oxygen atom, which are connected by covalent bonds. In class, we learn that elastic deformation is related to chemical bond stretching/distortion, and the covalent bonds should result in high Young's modulus. However, water is a liquid rather than a strong solid. Can you explain the seemingly discrepancy in the above cases?
