For a given level of significance, if the sample size increases, the probability of a Type II error will: a. remain the same. b. increase. c. decrease. d. be equal to 1.0 regardless of . ANS: C PTS: 1 REF: SECTION 11.3 151. The power of a test is measured by its capability of: a. rejecting a null hypothesis that is true. b. not rejecting a null hypothesis that is true. c. rejecting a null hypothesis that is false. d. not rejecting a null hypothesis that is false. ANS: C PTS: 1 REF: SECTION 11.3 152. If the probability of committing a Type I error for a given test is decreased, then for a fixed sample size n , the probability of committing a Type II error will: a. decrease. b. increase. c. stay the same. d. Not enough information to tell. ANS: B PTS: 1 REF: SECTION 11.3 153. The power of a test is denoted by: a. b. c. 1 - d. 1 - ANS: D PTS: 1 REF: SECTION 11.3 154.
