Yоu digress frоm yоur cаreer in medicine аnd become interested in venomous snаkes. You want to determine if the LD50 for the Black Mamba, Dendroaspis polylepis, (a very dangerous venomous snake from Africa) is different depending on which fang (right or left) delivers the venom. You carefully(!) take 8 snakes and measure the LD50 from the right and left fangs. You get the following results (in mg/kg): (Biology comment (not useful for answering the question!): LD50 is the dosage at which the venom kills 50% of the mice it's tested on (a bit gross, I admit)) Snake # 1 2 3 4 5 6 7 8 s right fang 0.973 1.070 0.719 1.289 0.642 0.889 1.039 0.944 0.946 0.203 left fang 0.235 1.286 1.714 0.054 1.299 0.478 0.920 0.157 0.768 0.623 difference 0.738 -0.216 -0.995 1.235 -0.657 0.411 0.119 0.787 0.178 0.764 You may assume that everything is normally distributed.
