So long as altitude, barometric strain and humidity keep on being frequent, a rise in air temperature will result in a flatter trajectory due to a reduce air density (significantly less collisions with ‘air particles’ for each device duration of flight path).
(one) The imply and standard deviation occur in two really distinct contexts. A single is as descriptive studies of a sample. As descriptive stats of a sample they have got say practically nothing about the mean and normal deviation of your populace unless one particular is aware of or assumes the populace density functionality and even further assumes the samples are random.
