O Because the p-value is greater than alpha, we reject the Ho. There is statistical evidence that attitudes on the bond issue are dependent on gender. Because the p-value is less than alpha, we fail to reject the Ho. There is not enough statistical evidence to prove that attitudes on the bond issue are dependent on gender. O Because the p-value is greater than alpha, we fail to reject the Ho. There is not enough statistical evidence to prove that attitudes on the bond issue are dependent on gender.
