4 +5 | power of 80% |

power of 80% Explanation: MJ, this might help: PODER - Power Es la probabilidad de que sea cierta la hipótesis nula. Se expresa como 1-Error beta. Si el Error beta es 0.2, 1-0,2=0.8 u 80%. Power analysis gives power for a specific effect size. For example, the researcher might report "If the treatment increases the recovery rate by 20 percentage points the study will have power of 80% to yield a significant effect". For the same sample size and alpha, if the treatment effect is less than 20 points then power will be less than 80%. If the true effect size exceeds 20 points, then power will exceed 80%.
