The best way for the biologist to estimate the population mean of the newborn elephants’ weights is to calculate the mean of 50 randomly selected weights in the table.

This method ensures that the sample is representative of the overall population and helps reduce bias that may occur if only the first few weights are used or a small, non-random subset is chosen. Randomly selecting weights gives a more accurate estimate of the population mean by capturing variability in the entire dataset.
