Accepted Answer

A parameter is a numerical characteristic of a population, while a statistic is a numerical characteristic of a sample.

Answer

A parameter is a fixed value, while a statistic is a random variable

Answer

A parameter is known, while a statistic is unknown

Question 18

What is the primary aim of hypothesis testing in econometrics?

Accepted Answer

To determine whether there is adequate evidence to reject or fail to reject a hypothesis.

Answer

To make predictions about the future

Answer

To estimate the parameters of a model

Question 19

What is the difference between a Type I error and a Type II error?

Accepted Answer

A Type I error occurs when a true null hypothesis is rejected, while a Type II error occurs when a false null hypothesis is not rejected.

Answer

A Type I error is accepting a true null hypothesis, while a Type II error is rejecting a true null hypothesis
