Problem 6: Consider the Blakley (3, w)-threshold scheme for which the following selections where made: 1. The number of users is w = 4 2. The secret $x_0 = 3$ 3. $p = 13$ 4. $y_0 = 1, z_0 = 4$ — picked at random from $Z_{13}$; that is, $Q = (3, 1, 4)$ 5. $a_1 = 1, b_1 = 1; a_2 = 4, b_2 = 2; a_3 = 3, b_3 = 0; a_4 = 5, b_4 = 9$, all picked at random from $Z_{13}$ (a) Find the shares given to each of the four users (b) Find the system of equations that the users 1, 2 and 3 need to solve to find the secret (c) Solve this system of equations to find the secret (does the system have a unique solution?).

A real estate agent wants to know how many owners of homes worth over \$1,000,000 might be considering putting their home on the market in the next 12 months. He surveys 71 of them and finds that 18 of them are considering such a move. Are all the assumptions and conditions for finding the sampling distribution of the proportion satisfied? Explain briefly. Choose the correct answer below. A. Yes; assuming the survey is random, they should be independent. The true proportion is about 0.25, and all other assumptions and conditions are met. B. No; since some of the owners of \$1,000,000 homes might be friends, if one of them is choosing to sell his house, the other might follow. Therefore, the observations are not independent. C. Yes; assuming the survey is random, they should be independent. Although the true proportion is not known so $np$ and $nq$ cannot be checked, with at least 10 successes and at least 10 failures, the Success/Failure Condition can be considered met. D. No; since the owner of a \$1,000,000 home can make much more money selling his house than the average homeowner, the observations are not independent.
