WebPower is probability that hypothesis test will correctly reject a false null hypothesis. A type II error is made when 1) Type II Error is made anytime we do not reject the null hypothesis. 2)Type II Error is made when there's not enough evidence to reject the null hypothesis and the null hypothesis is true. WebD) If p = 0.2 and α = 0.1, the inspector should accept the null hypothesis as the truth. Choose the correct statement. A) The larger the level of significance, the less likely you will fail to reject the null hypothesis. B) The larger the level of significance, the more likely you will fail to reject the null hypothesis.
