To explain what are the W’s for these data.
(a)
Explanation of Solution
It is given in the question that the bicycle helmet safety institute website includes a report on the number of bicycle fatalities in the U.S. the data per year is also given. Thus, the W’s for these data will be as:
Who: Bicycle helmet safety institute.
What: Bicycle fatalities per year.
Where: United States.
When:
Why: Report/track bicycle fatalities.
How: Reported accidents to the agency.
(b)
To display the data in a stem-and-leaf display.
(b)
Explanation of Solution
It is given in the question that the bicycle helmet safety institute website includes a report on the number of bicycle fatalities in the U.S. the data per year is also given. Thus, these data in the stem and leaf display is as:
Frequency | Stem | Leaf |
3 | 6 | 1 6 8 |
5 | 7 | 2 5 5 6 9 |
2 | 8 | 1 2 |

Explanation of Solution
It is given in the question that the bicycle helmet safety institute website includes a report on the number of bicycle fatalities in the U.S. the data per year is also given. Thus, the apparent in the stem and leaf display that is hard to see in the stem and leaf display is that more than half of the years had fatalities in a rage of
(e)
To find out what is apparent in the time plot that is hard to see in the stem and leaf display.
(e)
Explanation of Solution
It is given in the question that the bicycle helmet safety institute website includes a report on the number of bicycle fatalities in the U.S. the data per year is also given. Thus, the apparent in the time plot that is hard to see in the stem and leaf display is that as time goes on the amount of bicycle fatalities decreases.

- 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
