Question

Quizplus · Accepted Answer

The confidence interval for a population proportion is calculated as the sample proportion plus or minus the margin of error. The margin of error takes into account the desired confidence level and the variability in the sample. This approach allows for an estimation of the range within which the true population proportion is likely to fall, given a certain level of confidence.
