3. Students at a local high school wanted to know if natural eye color and natural hair color are independent of each other. They conducted a chi-square test for independence to study this issue, and after analyzing their data they found that their test statistic was not statistically signicant. Their conclusion then would be a. There is a difference between average eye color and average hair color. b. A person's hair color is dependent on their eye color. 0. There is not enough evidence to reject that hair color and eye color are independent
