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 approach provides a more representative sample of the entire population compared to simply taking the first 5 or 50 weights, which may not reflect the overall distribution. Random selection helps to minimize bias and increases the accuracy of the estimate of the population mean.
