Question
Chapter 15, Problem 15.16CYS
To determine
To identify: Whether the boldface number is a sampling distribution or statistic or parameter.
Expert Solution & Answer
Answer to Problem 15.16CYS
The correct option is (b) statistic.
Explanation of Solution
Given info:
The data shows that the percentage of people interviewed were employed is 4.9% and the sample number of households is 60,000.
Reason for correct answer:
Here, the percentage 4.9% is obtained by using the sample of 60,000 households and explains the characteristic of the sample.
Thus, the boldface number is a statistic.
The correct option is (b) statistic.
Reason for incorrect answers:
Since, the percentage 4.9% is obtained by using the sample the options (a) sampling distribution and (c) parameter are incorrect.
Conclusion:
Thus, the boldface number is statistic.
Statistics Concept Introduction
Introduction:
Sampling distribution:
It is the distribution of observations obtained by using the statistic of all the possible samples taken from the population. Here, the size of the all possible samples is same.
Parameter:
A parameter is a value that explains the characteristic of the population. In general, the parameter is estimated by using the sample, because it is difficult to examine the total population.
Statistic:
A statistic is a value that explains the characteristic of the sample. It can be obtained by using the sample of observations.

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].

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

T
K =

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…
