Dylan Mangino · Accepted Answer

Final Answer : B, Explanation :  Random samples provide good estimates of population averages if they have small variability. The smaller the variability, the more representative the sample will be of the overall population, and the more accurate the estimate of the population average will be. Therefore, option B, which states that random samples provide good estimates if they have small variability, is the best choice.
