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 102 Refer to the following hypothetical data collected using replicated measures design: Subject Pre Post 1 50 56 2 49 50 3 37 30 4 16 25 5 80 90 6 42 44 7 40 60 8 58 71 9 31 32 10 21 22 Refer to Exhibit 102. In a twotailed 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 ____. decrease s increases need more information equals zero
