Let G be a group containing 6 elements a, b, c, d, e, and f. Under the group operation called the multiplication, we know that ad=c, bd=f, and f^2=bc=e. Which element is cf? How about af? Now find a^2. Justify your answer.

Hint: Find the identify first. Then figure out cb.

Let the population have N=7 units, with {(unit,value)} = {(A,-1),(B,+1),(C,-2),(D,+3),(E,-4),(F,+5),(G,-6)}. The design is as follows: first choose A or B at random; if A then choose from {C,D} at random, if B then choose from {E,F,G} at random. 1) Find the first-order inclusion probabilities (note that the sample size n is fixed at 2). Verify (show numerically for this example) that the Horvitz-Thompson estimator is unbiased for the population total. (Hint: find the probability of each sample and the value...
