In other words, the red areas (area 0 and 8) sum to 5%. If the significance level alpha-5%, which area corresponds to the probability of correctly rejecting null hypothesis when the alternate hypothesis is true (i.e., the statistical power)? (assume a two-sided test) For your answer, select any areas that...
