Question
Chapter 3, Problem 119E
To determine
To explain: A report on the opinion on Online Behavioral Advertising.
Expert Solution & Answer
Answer to Problem 119E
Solution: The company should take informed consent before collecting data from the respondents. The company should also confirm that the data is used securely in the study and will be discarded after the completion of the study.
Explanation of Solution
In Online Behavioral Advertising, data about the online activity of individuals is recorded and different companies use the data to determine which advertisements should be targeted to a particular customer.
The four governing principles of data collection can be classified as transparency and control; security and data retention; privacy; and sensitive data.
Before collecting the data, the company should take informed consent. The procedure of data collection and the type of data to be collected should be stated clearly. It helps the company to keep transparency in the data collection process and also helps the company handle sensitive data. Consent should be taken from the respondents for ethical reasons because collection of data regarding the online behavior of the respondents without informing them is unethical.
If data about any personal details is collected from the respondents for the sake of the study, then the company should provide proper security to keep the data protected. The company should confirm to the respondents that the data from the study will be used by the company only and it will be discarded after the end of the study.

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…
