Many national parks, wildlife refuges, and wilderness areas lie directly below designatedmilitary air space. This raises issues of whether wildlife and loud jet noises are compatible.In an effort to evaluate the effects of low-altitude jet-noise, researchers simulated thesenoises for a representative sample of captive desert mule deer. Three minutes after the loudnoises were played, the heart rates (beats per minute) of these animals was measured, withthe following results:
a) Calculate and interpret a 95% confidence interval for the mean heart rate 3 minutes afterloud jet noises.
b) The usual mean heart rate for desert mule deer is about 51.2 beats per minute. Does theconfidence interval in part (a) support the view that the loud jet noise has some lingeringeffect on the heart rate of desert mule deer?
Explain, using appropriate statisticallanguage.
