The confidence interval half-width when π = 0.50 is called the margin of error.

Question

Quizplus · Accepted Answer

This statement is true. The margin of error is the range of values above and below the point estimate in which the true population parameter is expected to lie, with a certain degree of confidence. When the population proportion π is 0.50, the margin of error is at its maximum, as this is the point of maximum uncertainty about the population proportion.
