Question: Classroom assessment: Sampling and the population. Ryan (2006) reported about the effectiveness of an assignment given to students during a statistics class. The in-class assignment was aimed at helping students understand sampling distributions. In this study, participants selected 120 samples of size 3 from a population of 5 scores (0, 0, 0, 3, and 6) using the theoretical sampling strategy.
(a) How many possible samples can be drawn from this population?
(b) What is the population mean?
(c) What is the population standard deviation?
