In a study comparing two methods for reducing exam anxiety, 250250 students used a mindfulness app, 9595 of them reported significant anxiety reduction. 240240 students attended group counseling, 8080 of them reported significant anxiety reduction. Identify the null and alternative hypotheses for the claim that the two methods result in the same rate of significant anxiety reduction.

Problem 100Multiple Choice

In a study comparing two methods for reducing exam anxiety, $250$ students used a mindfulness app, $95$ of them reported significant anxiety reduction. $240$ students attended group counseling, $80$ of them reported significant anxiety reduction. Identify the null and alternative hypotheses for the claim that the two methods result in the same rate of significant anxiety reduction.
