Explanation Given: 10 quiz scores are given. Horizontal box plot-It is used for large data sets or for comparing several distribution. Parallel box plot drawn using the same number line provides the easiest comparison of medians, extreme scores and the quartiles for the set of data. Calculation: Arranging quiz score from least to highest 20 , 69 , 70 , 72 , 75 , 80 , 83 , 88 , 90 , 92 Median = 75 + 80 2 = 77.5 Q 1 = 70 Q 3 = 88 IQR = 88 − 70 = 18 Value Quiz score Maximum 92 Q 3

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…
