To calculate: the three conditional distribution of students smoking behaviour and describe and the relationship between the smoking behaviour of students and their parents
Answer to Problem 22E
Parents who do not smoke have comparatively the highest percentage of students who not smoke and parents who some have the comparatively highest percentage of students who smoke.
Explanation of Solution
Given:
Calculation:
Conditional distribution of students smoking behaviour for ‘Neither Parent Smoke’ is below:
Conditional Distribution of students smoking behaviour for parents smoking behaviour | ||||
Students Smoking Behaviour | Neither Parent Smoke | |||
Total No. | Percentage | |||
Student does not smoke | 1168 | 86.1 | ||
Student smokes | 188 | 13.9 | ||
Total | 1356 |
Conditional distribution of students smoking behaviour for ‘one parent smoke’ is below:
Conditional Distribution of students smoking behaviour for parents smoking behaviour | ||||
Students Smoking Behaviour | One Parent Smoke | |||
Total No. | Percentage | |||
Student does not smoke | 1823 | 81.4 | ||
Student smokes | 416 | 18.6 | ||
Total | 2239 | 100 |
Conditional distribution of students smoking behaviour for ‘both parents smoke’ is below:
Conditional Distribution of students smoking behaviour for parents smoking behaviour | ||||
Students Smoking Behaviour | Both Parent Smoke | |||
Total No. | Percentage | |||
Student does not smoke | 1380 | 77.5 | ||
Student smokes | 400 | 22.5 | ||
Total | 1780 | 100 |
From the above table of conditional distribution students smoking behaviour for parents smoking behaviour we conclude that parents who do not smoke (neither parent smoke) have comparatively the highest percentage of students who not smoke and parents who some (both parents smoke) have the comparatively highest percentage of students who smoke.
Conclusion:
Hence, that parents who do not smoke (neither parent smoke) have comparatively the highest percentage of students who not smoke and parents who some (both parents smoke) have the comparatively highest percentage of students who smoke.

(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
