A group of toxicologists investigated the impact of exposure to low oxygen on the mortality of rice weevils. In an
experiment, of rice weevils were found dead after exposure to nitrogen gas for 4 days. In a second
experiment, of rice weevils were found dead after exposure to nitrogen gas for 3.5 days. Conduct a test of
hypothesis to compare the mortality rates of adult rice weevils exposed to nitrogen at the two exposure times. Is there a
significant difference (at ) in the mortality rates?
