An employer interviews 9 people for 6 computer programming positions in a company, and 4 of the 9 people are men. If all 9 are qualified, in how many ways can the employer fill the computer programming positions if exact ...

Repeat given Exercise, using the following Aumann model of incomplete information with beliefs: N = {I, II}, Y = {1, 2, 3, 4, 5}, F I = {{1, 2}, {3, 4}, {5}}, F II = {{1, 3, 5}, {2}, {4}} P(ω) = 1/5, ∀ ω ∈ Y. for A = {1, ...

Let (N, Y, (F i ) i ∈N , s, P) be an Aumann model of incomplete information with beliefs, and let W ⊆ Y be an event. Prove that (N,W, (F i ∩ W) i ∈N , P(·  W)) is also an Aumann model of incomplete information with be ...

In this exercise we consider a situation with n men and n women. (a) Prove that if in stage t of the men's courtship algorithm, a particular man is dismissed for the (n  1)th time, then the algorithm terminates at stag ...

a. Using the table of critical values of t in Appendix A2, find the critical value of t for an experiment in which there are 28 participants, using an alpha level of .05 for a onetailed test b. Find the critical value ...

Prove that if Romeo and Juliet are matched to each other under both the men's courtship and the women's courtship algorithms, then they are matched to each other under any stable matching.

Imagine that you predicted a moderate correlation between people's scores on a measure of anxiety and the degree to which they report having insomnia. You administered measures of anxiety and insomnia to a sample of 30 p ...

If X and Y are statistically independent random variables both with probability density function f(t)=e^(t) I[0, +infinity](t) , where I is the indicator function of t. Find the probability density of the variable Z=Squ ...
