final answer:
The sample standard deviation, s, is a good point estimator for the population standard deviation, σ.
The answer is option ⇒2
Step-by-step explanation:
The sample standard deviation, s, is a statistic that estimates the variability of data in a sample. It measures how the individual data points differ from the sample mean.
For example, if you have a sample of test scores, the sample standard deviation can tell you how spread out the scores are from the average. So, in this case, the sample standard deviation, s, would be a good estimate for the population standard deviation, σ.
The answer is option ⇒2
