When carrying out a t test for independent means Group of answer choices the medians of the two populations are assumed to be equal. the null hypothesis is rejected if the computed t score is more extreme than the cutoff t score. only the .01 significance level should be used because of the greater power compared to a t test for dependent means. only the .10 significance level should be used because of the assumption that the variances of the two distributions should be equal.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !

if i put something wrong your not gonna like it so rather not say nothing.
