Estimation Is Best Defined As

question 124

Multiple Choice

Estimation is best defined as:

• A) a process of inferring the values of unknown population parameters from those of known sample statistics
• B) a process of inferring the values of unknown samples statistics from those of known population parameters
• C) any procedure that views the parameter being estimated not as a constant, but, just like the estimator, as a random variable
• D) a sampling procedure that matches each unit from population A with a "twin" from population B so that any sample observation about a unit in population A automatically yields an associated observation about a unit in population B
• E) both a process of inferring the values of unknown samples statistics from those of known population parameters and any procedure that views the parameter being estimated not as a constant, but, just like the estimator, as a random variable

Mean
