True or false? The best estimate of the population parameter (population mean) is the calculated sample average.

True

The statement 'the best estimate of the population parameter (population mean) is the calculated sample average' is true. It is because population mean and sample average are the same thing and are calculated by adding the sample values and dividing it by the number of total values. It is the best estimator because it gives the average of the sample population, which is more accurate than any other measures like median or mode.
