Given P-Value < 0.005, will you reject or fail to reject the null hypothesis of independence?


A) Since the P-value is greater than α\alpha , we fail to reject the null hypothesis that the Myers-Briggs personality preference and profession are not independent. At 0.01 level of significance, we conclude that the Myers-Briggs personality preference and profession are independent.
B) Since the P-value is greater than α\alpha , we fail to reject the null hypothesis that the Myers-Briggs personality preference and profession are independent. At 0.01 level of significance, we conclude that the Myers-Briggs personality preference and profession are not independent.
