Please note that for all problems in this course, the standardcut-off (alpha) for a test of significance will be .05, and youalways report the exact power unless SPSS output states p=.000(you’d report p<.001). Also, remember when hand-calculating,always use TWO decimal places so that deductions in grading won’tbe due to rounding differences.
