A researcher is determining the relationship between color preferences and gender. A sample of 40 men and 60 women is obtained and each person is asked to determine his/her preference between two choices of paint colors for the new student lounge. For this sample, 15 of the men preferred color A, and 35 of the women preferred color A. If a chi-square test is used to evaluate the relationship, what is the expected frequency for men preferring color A? Please explain your response.
