UESTION 11 If the effect size and the desired level of power are known, the power formula can be used to determine the O minimum meaningful difference. O number of participants needed. O population distribution. O alpha level of the experiment. UESTION 12 When conducting an experiment with 95% power, failing to reject the null hypothesis means that O there is no difference between the experimental and control populations the experiment was poorly conducted. null hypothesis is true. the chance that the data came from populations with a difference larger than that predicted when calculating
