Expert Solution & Answer
Explanation of Solution
The core plus mathematics program (CPMP) is an innovative approach to teaching mathematics. After field test in high schools over a three-year period, researchers compared the performances of CPMP students with those taught using traditional curriculum. The data given in the question is:
| Math Program | n | Mean | SD |
| CPMP | 320 | 57.4 | 32.1 |
| Traditional | 273 | 53.9 | 28.5 |
Thus, we conclude from the following given information that the students who chooses the CPMP are more than the students who adopt the traditional program. Also, the mean average score obtained by the students of CPMP is more than the average score obtained by the students of traditional program. Bu the variation in the scores of the students of CPMP is higher than the variation of the sores of the students of traditional program. Therefore, we can say that the CPMP is significantly more efficient than the traditional program.

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