Here are histograms of the values taken by three sample statistics in several hundred samples from the same population. The true value of the population parameter is marked on each histogram with an arrow. A B Which statistic has the lowest variability among these three? O Graph B because the graph of the sampling distribution is symmetric and level. O Graph C because the graph of the sampling distribution Is skewed to the right. O Graph A because the spread of the sampling distribution is small. O Graph A because the center of the sampling distribution is a perfect match for the parameter.
