Please note that for all problems in this course, thestandard cut-off (alpha) for a test of significance will be .05,and you always report the exact power unless SPSS output statesp=.000 (you’d report p<.001). Also, remember that we divide thep value in half when reporting one-tailed tests with 1 – 2groups.
