To calculate a sample proportion, we need to know the population size. - This is the true statement.
A sample statistic can never be equal to the population parameter. This is false. A statistic is a feature of sample and a parameter is a feature of population. Every sample of the selected size has an equal chance of being used.
Point estimates are defined for both samples and populations. This is false. A point estimate is used to estimate the population parameter.
To calculate a point estimate, we need to know the sample size. This is false. Population is needed.
Answer:
Option C is true. To calculate a sample proportion, we need to know the population size.
