The color vision of birds plays a role in their foraging behavior: birds use color to select and avoid certain types of food. the authors of a particular article studied the pecking behavior of 1-day-old bobwhites. in an area painted white, they inserted four pins with different colored heads. the color of the pin chosen on the bird's first peck was noted for each of 34 bobwhites, resulting in the accompanying table. do the data provide evidence of a color preference? test using α = 0.01.
