Determine the true state of cach statement. Choose from the choices below: C. Insufficient data A. True B. False D. Cannot be determined -. If a = 0.05 and the null hypothesis is true, we are about 95% confident that we would make the right decision. :The set of z-scores outside the range -1.96 to 1.96 constitutes what is called the critical region for 99% level of confidence. p2 0.2 can be considered as null hypothesis 4 < 0.2 can be considered as null hypothesis
