Question: 1. Suppose the population variance for a given population is 36. If we select all possible samples of a certain size from this population, then, on average what will be the value of the sample variance?
2. A researcher measures the time (in seconds) it takes a sample of five participants to complete a memory task. It takes four of the participants 5, 6, 6, and 7 seconds. If M = 6, then what must be the fifth time recorded?
