1. Let R be the relation on A = {1, 2, 3, 4, 5} given by R = {(1, 1),(1, 3),(2, 2),(2, 4),(2, 5),(3, 1),(3, 3),(4, 2),(4, 4),(4, 5),(5, 2),(5, 4),(5, 5)}. (a) Draw the digraph which represents R. (b) Give the 0 -1 matrix of R with respect to the natural ordering. (c) Which of the five properties (reflexive, irreflexive, symmetric, antisymmetric, transitive) does R have? Give a brief reason why or why not each property holds. 2. Let...

4) A high r squared or adjusted r squared does not mean a. The included variables are statistically significant. b. That you have an unbiased estimator. c. That you have an appropriate set of regressors. d. all of the above. 5) The adjusted r squared is different from the standard r squared in that it a. is always higher b. accounts for correlation between the error term, and the regressors c. corrects for degrees of freedom (number of regressors included...

4. (a) Suppose that τσ=(1 5 2 3)(4) and στ=(1 2 4 5)(3) in S5. If σ1 = 2, find σ and τ. (b) In Sn, show that σ = τ if and only if σ(τ)^(−1) = ε. ε is the identity permutation. Must be written as a proof. (c) Let σ=(1 2 3) and τ=(1 2) in S3. Show that S3={ε,σ,σ^2,τ,τσ,τ(σ)^2} and that σ^3=ε=τ^2 and στ=τ(σ)^2, then fill out the multiplication table for S3.
