PLEASE ANSWER ALL PLEASEEEEE
The presence of predators has been hypothesized to induce changes in prey behavior though chemical cues, even in the absence of direct interaction. Consider the graph below comparing activity levels of grey tree frog tadpoles, Hyla versicolor, reared either in the presence or absence of caged predators (dragonfly larvae, Anax longipes) in experimental ponds. Activity was quantified as the percentage of moving tadpoles observed over a 10-minute interval. Mean SE; n-30 tadpoles per experimental pond, F1, 10-6.12, P-0.033.Explanation / Answer
These data are consistent with the exixtance of nonlethal negative effects of predators on their prey.
given the reported statistical reports, would the null hypothesis be rejected with an alpha value of 0.05
yes with 95% confidence
the null hypothesis of the experiment is
D) decresed avarage percentage of tadpoles active in the rpesence of predators.
