Baby chicks are pecking at grains of cracked corn of different colors. A researcher is attempting to determine if they prefer one color over
another. He counts the number of grains chosen in an arena that has
equal numbers of red, blue, green and yellow corn chunks. The
expected number here is 235. Here are his results:
red: 250 blue: 220
green: 230
yellow: 240
Perform a Chi Square analysis on these results. Don't forget to find the
degrees of freedom. Make sure to show your work to get full credit.
