Chapter 4, Problem 99P
A study was performed to assess the feasibility of a national random digit dialing cellular phone survey among young adults age 18–34 (Genderson et al., [17]). It was reported that 3.1% of respondents were eligible to participate and that 52% of eligible respondents agreed to participate.
Suppose the survey is given to 100 subjects. What is the

Characterize (with proof) all connected graphs that contain no even cycles in terms oftheir blocks.
Let G be a connected graph that does not have P4 or C3 as an induced subgraph (i.e.,G is P4, C3 free). Prove that G is a complete bipartite graph
Prove sufficiency of the condition for a graph to be bipartite that is, prove that if G hasno odd cycles then G is bipartite as follows:Assume that the statement is false and that G is an edge minimal counterexample. That is, Gsatisfies the conditions and is not bipartite but G − e is bipartite for any edge e. (Note thatthis is essentially induction, just using different terminology.) What does minimality say aboutconnectivity of G? Can G − e be disconnected? Explain why if there is an edge between twovertices in the same part of a bipartition of G − e then there is an odd cycle
