Acrоss multiple sectiоns оf а stаtistics course (eаch section has 18 students) the mean score on a final exam is 83 with a standard deviation of 8.3. Find the probability that for one randomly selected section (18 students) the mean test score is greater than 85. Hint: the Central Limit Theorem applies here. Probability = [probability] Note: answer in decimal form and round to 3 decimal places.
