An Animal Population in a National Park Dropped from a High

Short Answer

An animal population in a national park dropped from a high of 232,000 in 1943 to a low of 76,000 in 1989, and has risen since then. Scientists hypothesize that the population follows a sinusoidal cycle affected by predation and other environmental conditions, and that the caribou will again reach their previous high. Predict the next year when the population will again be 232,000.
