Calculate the coefficient of determination for the following data set. Round your answer to three decimal places. ACT Scores and College GPAs ACT Score, x College GPA, y 16 1.85 18 2.20 24 2.80 25 3.50 34 4.00 27 3.18 29 3.90 25 2.90 30 4.00 21 2.60 17 2.50 21 3.65 28 3.10 31 3.72 35 3.24 18 2.30 17 1.70 26 3.10 28 3.50 23 2.76

n=20  

And in order to calculate the correlation coefficient we can use this formula:

And then the determination coeffcient would be:

From the info given we can calculate the following sums:

n=20  

And in order to calculate the correlation coefficient we can use this formula:

And then the determination coeffcient would be:

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.
