34% of CSU students participate in the Statistics Games while they attend CSU. You take a random sample of 40 students. You want to determine the probability that more than 15 of them have participated in the Statistics games. Since the conditions are met, you decide to use the Normal model to find your answer. What is the z-score for this problem? Hint: You need to use the Continuity Correction. Give your z-score to 2 decimal places.
