The confidence interval half-width when π = .50 is called the margin of error.

Question

Quizplus · Accepted Answer

The margin of error refers to the size of the confidence interval half-width when estimating a population proportion, and it is typically calculated using a formula that takes into account the sample size and level of confidence. When π = 0.50, the margin of error is typically highest (i.e., the confidence interval is widest), because this is the point of maximum uncertainty about the population proportion. Therefore, the statement that the confidence interval half-width when π = .50 is called the margin of error is true.
