The combined SAT scores for students taking the SAT-I test are normally distributed with a mean of 982 and a standard deviation of 192. Explain specifically why we could use the Central Limit Theorem to find the probability that a randomly selected sample of 9 students who took the SAT-I has a mean score between 800-1150 even though the same size is less than 30
