a)
Answer to Problem 1E
Median = 72 ounces and IQR = 40 ounces.
Explanation of Solution
Given:
Median = 68 ounces
IQR = 40 ounces
First, we need to understand about median and IQR.
Median: Median is the middle of the sorted data
IQR:
Therefore, the weight in each package increased by 4 ounces. So, median will change in the same way that all data values change.
Hence, median = 68+4 = 72 ounces.
It is known that, the data values all increase by the same value, the spread of the data values remains unaffected. Therefore, in this case, the IQR remains unchanged.
Hence, IQR = 40 ounces.
b)
To convert median and IQR into pounds instead of ounces.
b)
Answer to Problem 1E
Median = 4.5 pounds and IQR = 2.5 pounds.
Explanation of Solution
Given:
Median = 72 ounces
IQR = 40 ounces
1 lb = 16 oz.
Calculation:
First, we need to understand about median and IQR.
Median: Median is the middle of the sorted data
IQR: Interquartile
Therefore,
And

- solve the question based on hw 1, 1.41arrow_forwardT1.4: 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_forward
