Question
Chapter 3, Problem 1CRE
a.
To determine
To find: The explanatory and response variables involved in the study.
a.
Expert Solution
Answer to Problem 1CRE
The probability is 0.875.
Explanation of Solution
Given:
A study has been conducted to check if obese people are more likely to die in comparison of people who weigh less. A possible confounder is that the obese people are inactive and lazy
Calculation:
In this case, mortality rate is the response variable because it is dependent on the weight of the people. Thus, it could be conclude that mortality rate is a response variable and weight is an explanatory variable.
b.
To determine
To explain: Whether it could be concluded that weight is causing the increase in risk of death
b.
Expert Solution
Answer to Problem 1CRE
No.
Explanation of Solution
Calculation:
Here, it cannot be said that weight is causing the increase in risk of death because there are various lurking factors like activity and wealth which may affect the weight and mortality rate. Thus, it is not possible to agree with the provided statement.

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_forwardNegate the following compound statement using De Morgans's laws.arrow_forward
