![As the world warms, the geographic ranges of species might shift toward cooler areas. Chen et al. (2011) studied recent changes in the highest elevation at which species occur. Typically, higher elevations are cooler than lower
elevations. Below are the changes in highest elevation for 20 of the 31 taxa examined in this study, in meters, over the late 1900s and early 2000s. (Taxa included plants, vertebrates, and arthropods.) Positive numbers indicate upward
shifts in elevation, and negative numbers indicate shifts to lower elevations. The values are also displayed in the attached graph. What is the standard error of the mean of elevational range shift in these 20 species? (Do not include
units, but remember they are meters), and express answer to 3 significant digits)
