A researcher tests the effect of mediation training on sleep quality, as measured by WASO (Wakefulness after sleep onset). She performs a randomized experiment; one group receives meditation instructions, and one receives sham instructions. She plans to test H₀: No difference in WASO, against the undirected H₁: There is a difference, at a significance level of 5%. She obtains a one-sided p value of 0.03 and claims a significant effect. Do you agree? Why/ Why not?
