[Solved] Test Hypotheses Regarding Two Population Standard Deviations -A medical researcher suspects that the variance of the pulse rate of drinkers is higher than the variance of the pulse rate of non-drinkers. Use the sample statistics below to test the researcher's suspicion. Use \(\alpha = 0.05\) Assume the samples were randomly selected from normal populations. Tectonic Plates: Large pieces of the Earth's crust that move, float, and sometimes fracture and whose interaction causes continental drift, earthquakes, volcanoes, mountains, and oceanic trenches. Ejecta: Material that is expelled or thrown out, especially as a result of volcanic eruption, meteorite impact, or other explosive events. Sedimentary: Pertaining to rocks formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by compaction. Sandstone: A sedimentary rock composed mainly of sand-sized minerals or rock grains.
