Explain why the margin of error determines the accuracy with which a sample mean estimates a population mean.

The answer is below

Step-by-step explanation:

Given that Margin of error is a term applicable in statistics that describe the extent of error calculated from a random sampling analysis or research.

It, therefore, determines the accuracy with which a sample mean estimates a population mean with a predefined degree of confidence, the population means is within the margin of error of the sample mean.

This implies that a higher margin of error than the specified degree of confidence will equate that the results of such a survey are not reliable.
