The trials are done without replacement is NOT a requirement for constructing a confidence interval for estimating the population proportion.

Option D

Explanation:

The confidence interval (CI) for a population proportion is a statistical term which describes the probability that a certain character is likely to occur within the population. It is normally determined by measuring or estimating the percentage of the population that falls within a certain category.

For example, it can be a percentage of drivers who never wear their seatbelts while driving or a percentage of Democrats who participated in the last election. The formula for (CI) is a subject of the sample mean, standard deviation, the desired confidence value and population sample and etc.
