A large school district in Connecticut wants to estimate the average SAT score of this year’s graduating class using a confidence interval. The district takes a simple random sample of 100 seniors. The sample mean is 510 and the population standard deviation for SAT scores is known to be 75. They want an interval that "likely" contains the true mean, where "likely" means "the procedure has a 68% success rate". What is the margin of error for this confidence interval?
