From the year 2005 to the year 2015, the production of corn in a certain state has increased by \(15 \%\). During the same interval, the production of wheat has fallen by \(40 \%\).

A recent biological study performed on a large random sample of North American birds found that \(46 \%\) of birds' nests experienced full or partial nest predation, in which some type of predator raided the nest before the hatchlings had flown off. The margin of error for the study was \(3 \%\). Which of the following is the best interpretation of the margin of error for this study? A) The percentage of North American birds whose nests get raided by predators is likely somewhere between \(43 \%\) and \(49 \%\). B) There is a \(3 \%\) chance that the study's finding about nest predation for North American birds is incorrect. C) It is unlikely that fewer than \(43 \%\) of birds' nests will get raided this coming year. D) The research indicates that no more than \(49 \%\) of birds' nests will likely get raided by predators.
