Problem 2E

A geologist is making repeated measurements (in grams) on the mass of a rock. It is not known whether the measurements are a random sample from an ap- proximately normal population. Below are three sets  of replicate measurements, listed in the order they were made. For each set of readings, state whether the assumptions necessary for the validity of the t test  appear to be met. If the assumptions are not met, explain why.
