The black‑capped chickadee (Poecile atricapilla) is a small songbird commonly found in the northern United States and Canada. Chickadees often live in cooperative flocks, using a complex language to communicate about food sources and predator threats. In an experiment, researchers recorded chickadee vocalizations in an aviary when presented with predators of various sizes. The table contains data representing the average number of D notes per chickadee warning call for each type of predator, along with the predator wingspan (in centimeters). The researchers also recorded chickadee calls in response to the introduction of a bobwhite, a harmless quail. The bobwhite has a wingspan of 48.1 cm and the chickadees responded with an average of 1.74 D notes per call. Use the software of your choice to find the new correlation when the data point for the bobwhite is included. (Enter your answer rounded to four decimal places.)
