Question
Chapter 17, Problem 1TP
To determine
To explain: The case when obtained chi-square value is zero with an example.
Expert Solution & Answer
Answer to Problem 1TP
The value of chi square will be zero if the expected frequency becomes equal to the obtained frequency.
Explanation of Solution
When a first year student completed his mathematics exam and expecting that will get 90% score. If the student scored 90% in his mathematics exams, in this situation expected frequency will be equal to the obtained frequency. The value of chi square will be zero in this case.

solving problem 1
select bmw stock. you can assume the price of the stock
This problem is based on the fundamental option pricing formula for the continuous-time
model developed in class, namely the value at time 0 of an option with maturity T and
payoff F is given by:
We consider the two options below:
Fo=
-rT
= e
Eq[F].
1
A. An option with which you must buy a share of stock at expiration T = 1 for strike
price K = So.
B. An option with which you must buy a share of stock at expiration T = 1 for strike
price K given by
T
K =
T
St dt.
(Note that both options can have negative payoffs.) We use the continuous-time Black-
Scholes model to price these options. Assume that the interest rate on the money market
is r.
(a) Using the fundamental option pricing formula, find the price of option A. (Hint:
use the martingale properties developed in the lectures for the stock price process
in order to calculate the expectations.)
(b) Using the fundamental option pricing formula, find the price of option B.
(c) Assuming the interest rate is very small (r ~0), use Taylor…
