The correct answer is - Large numbers of migratory birds;
The number of the migratory birds has always been pretty high and it hadn't resulted in the drying up of the Ogallala Aquifer, not to mention that those birds can not even reach that water because it is underground. Also, the number of the migratory birds have been steadily lowering, so even if they were using that water for drinking, it wouldn't have caused the drying out.
The Ogallala Aquifer has started to dry out because of numerous reasons, with the usage of its water for irrigation being the prime reason. The droughts have become longer, and the temperatures little higher, while the rainfall slightly smaller, so all of that affected the reserves of water in the aquifer negatively.
The correct answer is <span>the values are measures for the sampling distribution of the mean
For example, in the </span>μm it is used to<span> represent the mean of the distribution of sample </span>means, while in the σm it is indicated that this value is a standard deviation, and just the M means that it is the standard deviation for the distribution of sample <span>means</span>
