In a study of the effects of mediation on anxiety, participants were randomly assigned to either engage in a mindfulness meditation session for 5 minutes or to sit quietly for 5 minutes. All participants then completed an anxiety measure. The researchers predicted that there would be a difference in anxiety scores between the two groups. Which would be the appropriate null hypothesis? a. H0: u 1 > u 2 b. H0: u 1 = u 2 c. H0: u 1 < u 2 d. H0: u 1 > u 2
