   Question

   It is assumed that the correlation between two tests X and Y that both measure intelligence is 0.80. In a random sample of n = 50 individuals, one finds R_XY = 0.71. Based on this result, the null hypothesis ρ_XY = 0.80 can be rejected in favor of the alternative hypothesis ρ_XY < 0.80 at

   
   
   1. FALSE: Α = 0.01
   2. FALSE: Α = 0.05 but not at α = 0.01
   3. TRUE: Α = 0.10 but not at α = 0.05
   
   
   1. Α = 0.01: Incorrect
   2. Α = 0.05 but not at α = 0.01: Incorrect
   3. Α = 0.10 but not at α = 0.05: Correct
