Researcher Lawrence develops a new emotion regulation intervention for reducing employees' anxiety. She knows that scores on a well-validated measure of anxiety are normally distributed with u = 15 and o = 5. Researcher Lawrence administers her new emotion regulation intervention to a sample of n = 64 workers who subsequently score M = 25.5 on the measure of anxiety. Which conclusion can she make based on the results of this research study? The new intervention has an effect on anxiety because the computed z-score does not surpass the z = +1.96 threshold. The new intervention has an effect on anxiety because the computed z-score surpasses the z = +1.96 threshold The new intervention does not have an effect on anxiety because the computed z-score does not reach the z = +1.96 threshold. The new intervention does not have an effect on anxiety because the computed z-score reaches the z = +1.96 threshold.
