The sat critical reading score is normally distributed in the population (for all students who take the sat), with a mean sat critical reading score of 503 and a standard deviation of σ = 115. a random sample of 100 test takers who were classified as english language learners had a mean sat critical reading score of 485 and a standard deviation of 116. do these results suggest that english language learners score worse than the population of all students who take the sat critical reading exam?
