Explanation Calculation: It is given that in a survey RP Web sites were categorized as server-flow or client-flow Web sites. 20 were found to be vulnerable to an impersonation attack among 40 server flow sites. 41 were found to be vulnerable to an impersonation attack among 54 client flow sites. Denote p 1 is the proportion of server flow sites that are vulnerable to an impersonation attack, and p 2 is the proportion of client flow sites that are vulnerable to an impersonation attack. The hypotheses are given below: Null hypothesis: H 0 : ( p 1 − p 2 ) = 0 There is no significant difference between the proportions of server flow sites and client flow sites that are vulnerable to an impersonation attack. Alternative hypothesis: H a : ( p 1 − p 2 ) < 0 The proportion of client–flow sites is significantly greater than the proportion of server–flow sites that are vulnerable to an impersonation attack. Level of significance, α = 0.01. Software Procedure: Step-by-step procedure to test two proportions using the MINITAB software: Choose Stat > Basic Statistics > 2 Proportions . Choose Summarized data

T1.4: Let ẞ(G) be the minimum size of a vertex cover, a(G) be the maximum size of an independent set and m(G) = |E(G)|. (i) Prove that if G is triangle free (no induced K3) then m(G) ≤ a(G)B(G). Hints - The neighborhood of a vertex in a triangle free graph must be independent; all edges have at least one end in a vertex cover. (ii) Show that all graphs of order n ≥ 3 and size m> [n2/4] contain a triangle. Hints - you may need to use either elementary calculus or the arithmetic-geometric mean inequality.

We consider the one-period model studied in class as an example. Namely, we assumethat the current stock price is S0 = 10. At time T, the stock has either moved up toSt = 12 (with probability p = 0.6) or down towards St = 8 (with probability 1−p = 0.4).We consider a call option on this stock with maturity T and strike price K = 10. Theinterest rate on the money market is zero.As in class, we assume that you, as a customer, are willing to buy the call option on100 shares of stock for $120. The investor, who sold you the option, can adopt one of thefollowing strategies: Strategy 1: (seen in class) Buy 50 shares of stock and borrow $380. Strategy 2: Buy 55 shares of stock and borrow $430. Strategy 3: Buy 60 shares of stock and borrow $480. Strategy 4: Buy 40 shares of stock and borrow $280.(a) For each of strategies 2-4, describe the value of the investor’s portfolio at time 0,and at time T for each possible movement of the stock.(b) For each of strategies 2-4, does the investor have…
