Question

Samples A and B were selected from the same population. The mean of sample A is equal to the mean of the population. Which of the following statements must be true? The mean of sample A is a point estimator for the mean of the population. The mean of sample B is a point estimator for the mean of the population. The mean of sample A is equal to the mean of sample B.

Answer 1

Answer:

The mean of sample A is a point estimator for the mean of the population.

Explanation:

Answer 2

Since the Sample A & B were selected from the same population, then, the true statement will be "mean of sample A is a point estimator for the mean of the population".

In statistics, point estimator is a measured used to estimate the value of an unknown parameter of a population.

Hence, the true statement will be "mean of sample A is a point estimator for the mean of the population".

Therefore, the Option A is correct.
