A normal population has a mean of µ = 80 with σ = 20. a. If a single score is randomly selected from this population, how much distance, on average, will be found between the score and the population mean? b. If a sample of n = 25 scores is randomly selected from this population, how much distance, on average, will be found between the sample mean and the population mean? c. If a sample of n = 100 scores is randomly selected from this population, how much distance, on average, will be found between the sample mean and the population mean?
