The sample mean is the best point estimate of the population mean.

This is because the sample mean provides the most unbiased and consistent estimate of the population mean based on the data collected from the sample.

Would you like further details or have any specific questions? Here are some related queries to explore:

1. Why is the sample mean considered an unbiased estimator of the population mean?
2. How does sample size affect the reliability of the sample mean as an estimate of the population mean?
3. What are other methods to estimate the population mean, and when are they used?
4. How is the standard error related to estimating the population mean?
5. What assumptions must be met for the sample mean to be a good estimator?

Tip: Always check the representativeness of your sample to ensure accurate estimation of population parameters.
