Rodents A scientist is interested in studying the effects that applying pesticide to crops has on the local rodent population.

The scientist collects 31 rodents from the field where the pesticide is used and finds the mean weight of this sample to be 84.6 grams.

Assuming the selected rodents are a random sample, he concludes that because the sample mean is an unbiased estimator of the population mean, the mean weight of rodents in the population is also 84.6 grams.
