Question
Often the percent of an animal species in the wild that survive to breed again is lower following a successful breeding season. This is part of nature’s self-regulation, tending to keep population size stable. A study of merlins (small falcons) in northern Sweden observed the number of breeding pairs in an isolated area and the percent of males (banded for identification) who returned the next breeding season. Here are data for eight years:

Percent

The aim is to test if the percent of males returning in the next breeding season decreases linearly with the number of breeding pairs.
The P-value is about 0.3899 and the correlation value is about -0.1184. What is your conclusion at the 0.05 level of significance?
We do not reject that the percent of males returning in the next breeding season decreases linearly with the number of breeding pairs.
We reject that the percent of males returning in the next breeding season decreases linearly with the number of breeding pairs.
There is not enough information. We need the value of the test statistic to make any conclusions.
