The variance of the empirical distribution is o2 = Var[x] = - 27=1(x; 7)? This is different from the sample variance sa (n-1)=?=1(x; 7)2 1. Is the variance of the empirical distribution biased or unbiased? Prove it (20 points) 2. Discrepancies can exist between a population and the samples you obtain from it. This leads to error. Describe an example of sampling error and an example of non- sampling error (15 points). xxxxxxxx(xxxxxxxx OK 3. Below is depicted images of two objects, a chocolate Labrador retriever dog and a sheep. Describe how they might differ from the perspective of their appearance based feature representation (15 points). The variance of the empirical distribution is o2 = Var[x] = - 27=1(x; 7)?
