Unformatted text preview: CHAPTER 11 SECTION 3: INTRODUCTION TO HYPOTHESIS TESTING MULTIPLE CHOICE 150. 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 α . 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. α b. β c. 1 - α d. 1 - β ANS: D PTS: 1 REF: SECTION 11.3 154. For a given sample size n , if the level of significance α is decreased, the power of the test will: a. increase. b. decrease. c. remain the same. d. Not enough information to tell. ANS: B PTS: 1 REF: SECTION 11.3 155. For a given level of significance α , if the sample size n is increased, the probability of a Type II error β will: a. decrease. b. increase. c. remain the same. d. Not enough information to tell.

If we want to compute the probability of a Type II error, which of the following statements is false? a. We need to know the significance level α . b. We need to know the sample size n . c. We need to know the alternative value of the population mean μ . d. All of these choices are true....
