e) T F The larger the sample that is taken, the probability of making a type 2 error increases. f) T F We can never conclude that H0 is true based on taking a random sample from from the population. g) T F A stratified random sample is more preferred over a simple random sample when the population can be divided into homogeneous groups.

1) a) Let k ≥  2 and let G be a k-regular bipartite graph. Prove that G has no cut-edge. (Hint: Use the bipartite version of handshaking.) b) Construct a simple, connected, nonbipartite 3-regular graph with a cut-edge. (This shows that the condition “bipartite” really is necessary in (a).) 2) Let F_n be a fan graph and Let a_n = τ(F_n) where τ(F_n) is the number of spanning trees in F_n. Use deletion/contraction to prove that a_n = 3a_n-1 - a_n-2...
