To determine this, they gathered lizards from eastern Arkansas (where there were no fire ants), and from southern Alabama (which had been invaded by fire ants). The lizards were then exposed to fire ants, and researchers measured how long (in seconds) it took the lizards to flee. What does each dot represent? Choose the best answer. Choice 1:A difference in time to flee for a single lizard from Alabama, and a single lizard from Arkansas, assuming the null hypothesis is true. Choice 2:A difference in mean response times for one sample of lizards from Alabama, and one sample of lizards from Arkansas, which was likely to occur if the null hypothesis is true. Choice 3:A difference in response times for two lizards in our sample. Choice 4:The proportion of all lizards who will free from fire ants. Which Choice is most correct and why?
