Using the sign test, if (1) H1 is directional, (2) H0 is false, (3) = 0.01, and (4) N = 12, then the probability of making a Type I error equals ____. 0.0002 0.0010 0.0192 0 In a nondirectional alternative hypothesis, evaluating the probability of observing 7 pluses out of 8 events equals ____. p(7) + p(8) p(0) + p(8) p(0) + p(1) + p(7) + p(8) p(7) Exhibit 10-2 Refer to the following hypothetical data collected using replicated measures design: Subject 1 2 3 4 5 6 7 8 9 10 Pre 50 49 37 16 80 42 40 58 31 21 Post 56 50 30 25 90 44 60 71 32 22 Refer to Exhibit 10-2. In a two-tailed test of H0 using = 0.05, what is p(obtained) for the results shown? 0.1094 0.0108 0.0500 0.0216 In an experiment in which H1 is nondirectional, and the state of reality is such that the probability of a plus = 0.50, the probability of making a Type II error is ____. 0 1 alpha 1 need more information If H1 is nondirectional and the size of the effect of the independent variable decreases, the probability of making a Type I error ____. decreases increases need more information equals zero
