   Question

   We want to test the hypothesis H₀: μ₁= μ₂ against the one-sided alternative H₁:μ₁ < μ₂ with risk α = 0.05, using a pooled T-test. To this end, we draw two samples, both of size 10, from the corresponding populations. The limit of the critical area is then

   
   
   1. FALSE: -2.1009
