Answer to Problem 26E
Median would be affected marginally.
The mean would be skewed download.
Explanation of Solution
Median would be affected marginally.
The mean would be skewed download.
The median would not be change. The lowest temperature was the lowest temperature already, and it simply got lower. Its placement in the data was always 1st, when ordered, so the median does not change. The mean, however, is the average of all values. Replacing one value with a much smaller value will cause the mean to decrease.

Expert Solution
Answer to Problem 26E
The range will increase significantly
The IQR will not change.
The standard deviation will increase significantly.
Explanation of Solution
The range will increase significantly (by 34, to be exact).
The IQR will not change.
The standard deviation will increase significantly.
The range is the highest number minus the lowest. If the lowest number decreases significantly, the range would increase by the change. The IQR only counts the first and third

(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_forward
- 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.
