Final answer:
The point estimator for the population variance is s². The sample variance, s², is a good point estimator for the population variance.
The answer is option ⇒2
Step-by-step explanation:
A point estimator is a single value that estimates a parameter. In this case, we are estimating the population variance. The sample variance, denoted by s², is a good point estimator for the population variance.
For example, if we have a sample of data and calculate the sample variance, it gives us an estimate of the population variance based on that sample. The point estimator for the population variance is s².
The answer is option ⇒2
