Question

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

Answer 1

Answer: A) A sample statistic can never be equal to the population parameter.

Step-by-step explanation:

Answer 2

The statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.

The following statements should not be considered:

• The statistic of the sample should be equal to the parameter of the population as the statistic represent the attribute of the sample and the parameter represent the parameter of the population. Also, each and every sample should have an equivalent chance of using it.
• The estimation of the point does not define the sample & population as the estimation of the point should be predicted for the parameter of the population.
• For determining the point estimate, the sample size does not need as the population is required.

Therefore we can conclude that the statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.
