Question

Quizplus · Accepted Answer

The sample mean is the best point estimate of the population mean as it is calculated using a representative subset of the population and provides an estimate of the central tendency of the entire population. Option A is incorrect as the sample mean cannot estimate the population standard deviation without additional information. Option B is incorrect as the sample mean is not a point estimate of the population median, which is the middle value of a population. Option D is incorrect as the sample standard deviation estimates the variability of the sample, not the population.
