A researcher is conducting a chi-square test for independence to evaluate the relationship between gender and preference for three different designs for a new automobile. Each individual in a sample of 30 males and 30 females selects a favorite design from the three choices. If the researcher obtains a chi-square statistic of c2 = 4.81, what is the appropriate statistical decision for the test?
