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 n = 30 males and n = 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?

Reject the null hypothesis with a = .05 but not with a = .01

Reject the null hypothesis with either a = .05 or a = .01

Fail to reject the null hypothesis with either a = .05 or a = .01

There is not enough information to determine the appropriate decision.
