Suppose a researcher is conducting a two-way Chi-square test to evaluate the relationship between gender and preference among 4 different designs for a new automobile. Each participant in a sample of 40 men and 40 women selects a favorite design from the 4 choices. If the researcher obtains a calculated value of Chi-square of 9.68, what is the appropriate statistical decision for the test? A. Reject the null hypothesis at the .05 level of significance but fail to reject the null hypothesis at the .01 level of significance B. Fail to reject the null hypothesis at the .05 level of significance and at the .01 level of significance Reject the null hypothesis at the .05 level of significance and at the .01 level of significance D. Impossible to answer without additional information C.
