A0.05 significance level is being used to test a correlation between two variables. if the linear correlation coefficient r is found to be 0.591 and the critical values are r equalsplus or minus0.878, what can you conclude? there is not sufficient evidence to support the claim of a linear correlation between the two variables. there is sufficient evidence to support the claim of a linear correlation between the two variables.

Step-by-step explanation:

Given that the linear correlation coefficient r is found to be 0.591

the critical values are r equals plus or minus 0.878.

Significance level used = 0.05

The correlation r = 0.591

(two tailed test)

Test statistic =

Since r is less than 0.878, we accept that there is linear correlation between the two variables.

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.
