Question
Chapter PIII, Problem 22RE
(a)
To determine
To Explain: that this is a experiment or study.
(a)
Expert Solution
Explanation of Solution
This was an experimental study because it manipulates the one factor that is radio waves and produces the treatments and assigns subject to these treatment levels randomly, meaning that as a result of the three treatments, it has three levels that are digital cell phone radio waves, traditional cell phone radio waves and no radio waves. The occurrence of brain tumours is the liable predictor.
(b)
To determine
To Explain: the meaning of not statistically significant.
(b)
Expert Solution
Explanation of Solution
Not statistically relevant in this sense means that the disparity in tumour incidence between three groups of rats was not sufficient to convince researchers that the differences were due to something other than variability in sampling.
(c)
To determine
To explain: the fact that Motorola, a mobile phone maker, sponsored this study.
(c)
Expert Solution
Explanation of Solution
This research was discovered by Motorola. A mobile phone maker who may have demonstrated bias. The researchers in this experiment have felt the urge to announce that the mobile phone is safe.

- 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.arrow_forwardWe 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…arrow_forwardNegate the following compound statement using De Morgans's laws.arrow_forward

Prove that G is a complete bipartite grapharrow_forwardProve 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?

At time T = 1 year, the stock has either moved up to S1 = 8 (with probability0.7) or down towards S1 = 2 (with probability 0.3).
