Answer #1

Here the waiting times, is for 1 patient at a time. We are not testing two populations and neither are we testing the same patient for 2 different times.

Therefore the parameter of interest here is m, the mean of one sample.

The parameter is the mean waiting time of the 100 patients who have been waiting at the GMU health center and who represent the population from which they have been sampled.
