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.
The data set of readings is as follows: 213.05, 213.00, 212.94, 213.09, 212.98, 213.02, 213.06, 212.99. The assumptions necessary for the validity of the t test appear to be met.
a. True
b. False
