The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to …

If the parameter we're trying to estimate is the population mean, then our statistic is going to be the sample mean. So, in that scenario we're going to be looking at, our statistic is our sample mean plus …
