Question

One of nature's patterns connects the percent of adult birds in a colony that return from the previous year and the number of new adults that join the colony. The data for 13 colonies of sparrowhawks are in the table.

Percent return	74	70	86	56	77	60	51	44	63	44	62	49	33
New adults	6	6	8	11	14	14	17	16	19	18	18	19	21

Use the software of your choice to find the correlation between the percent of returning birds and the number of new birds. (Enter your answer rounded to three decimal places.)

correlation:

The original data (green) and two new points are in the scatterplot. Point ? (blue) is 13% return, 26 new birds. Point ? (red) is 35% return, 11 new birds.

Find the new correlation for the original data plus Point ? . (Enter your answer rounded to three decimal places.)
