In order to determine which of the data represent an extreme distribution, the data have to graphed in value vs density graph. After doing this, the shape parameter of the graph is determined. For shape parameters equal to - 1/2, 0, and + 1/2, the distribution is extreme. The answer is B. Marathon C
