Refer to Exercise 15.61. Using the original data (not combining green and hazel), construct a contingency table for the two variables:

Explanatory variable: Eye color.

Response variable: Finds own eye color most attractive, yes or no.

a. Conduct a chi-square test to determine if these two variables are related. Specify all five steps of the test.

b. Determine which eye color (as respondent’s own color)

contributes the most to the chi-square statistic. Explain whether that eye color is more attractive to people who have it as their own eye color than would be expected under the null hypothesis, or less so.
