In 1997 it was thought 35% of people had brown eyes, 45% had blue eyes, 15% had green eyes, and 5% had a color different than these three. A recent study done on 120 randomly selected people found that 41 had brown eyes, 60 had blue eyes, 16 had green, and the rest had a different color than these three. If a test of the claim that the 1997 distribution of eye color is significantly different than the recent distribution is performed this is the value of the test statistic.
