Which statement is true?
A sample statistic can never be equal to the population parameter.
Point estimates are defined for both samples and populations.
To calculate a sample proportion, we need to know the population size.
To calculate a point estimate, we need to know the sample size

Respuesta :

Answer:

Option C is true. To calculate a sample proportion, we need to know the population size.

Step-by-step explanation:

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.

The correct statement state that: To calculate the point estimate, the sample size is required.

What is Point Estimate?

The Point Estimate of a population is the single value of a statistic. This refers to the single value given as an estimate of a parameter.

Always note that Point Estimate is always computed from the sample, and therefore, always dependent on the sample.

Simply defined, Sample Size is the of observations and or participants included in a study or research.
The correct answer, thus, is D.
