A group of toxicologists investigated the impact of exposure to low oxygen on the mortality of rice weevels. 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, 23,516 of 23,676 rice weevils were found dead after exposure to nitrogen gas for 4 days. In a second experiment, 23,516 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 itrogen and the two exposure times. Is there a significant difference (at a=0.10) in the mortality rates?
**Give the null and alternative hypotheses. Let p^1 represent the proportion of rice weevils found dead in the first experiment and p^1 represent the proportion of rice weevils found dead in the second experiment. Choose correct answer below*****
A) H^0: (p^1-p^2)>0, H^a(p^1-p^2)=0
B) H^0:(p^1-p^2) =/ (does not equal) , H^a: (p^1-p^2)=0
C) H^0:(p^1-p^2)=0, H^a: (p^1-P62)=0, H^a:(p^1-p^2)<0
D) H^0:(p^1-p^2)=0, H^a:(p^1-p^2)>0
E) H^0:(p^1-p^2)<0, H^a: (p^1-p^2)=0
F) H^0:(p^1-p^2)=0, H^a:(p^1-p^2) =/ (does not equal) 0
