2. 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 approximately 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.
a. 213.03 212.95 213.04 213.00 212.99
213.01 221.03 213.05
b. 213.05 213.00 212.94 213.09 212.98
