Agroup of toxicologists investigated the impact of exposure to low oxygen on the mortality of rice weevils. In an experiment, 31,388 of 31,421 rice weevils were found dead after exposure to nitrogen gas for 4 days. In a second experiment, 23,515 of 23,676 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 signicant difference (at or = 0.10) in the mortality rates? Give the null and alternative hypotheses. Let p1 represent the proportion of rice weevils found dead in the rst experiment and p2 represent the proportion of rice weevils found dead in the second experiment. Choose the correct answer below. 0 A. H0: (p1p2) =0 0 B. H0: (p1 p2) =0 Ha: (9192] 0 O C. H0: (p1p2) =0 0 D. H0: (p1 p2) >0 Ha: (p1p2) #0 Ha: (p1 p2) =0 0 E. H0: (p1p2) #0 O F. H0: (p1 p2)
