GPT-4o mini · Answer

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 allows for a larger sample size, which generally provides a more accurate estimate of the population mean, and random selection helps to reduce bias in the sample.
