Chapter 6, Problem 1PP
To determine
To explain identify the True statement.
Expert Solution & Answer
Answer to Problem 1PP
Statement A is true “Sampling bias increases the chance of committing Type 1 Error.”.
Explanation of Solution
Given:
The statements:
- Sampling bias increases the chance of committing Type 1 Error.
- There is no effect on probability of Type 1 Error due to sampling error.
Type 1 Error refers to the rejection of True null hypothesis. Which means a researcher rejects the null hypothesis when it is actually true. It is also known as the level of significance and it is denoted by
Factors that affect the chance of committing type 1 error are given below:
Sample Size - Level of significance
If the sampling error is higher means that the difference between estimated parameter and the true parameter are higher which means larger the value of test statistics and larger statistics value means lower the P value and P value is the maximum value of level of significance. Therefore, increase in sampling error implies decrease in the type 1 Error.
Therefore Option A is correct.

- 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.)
