The table above shows a random sample of SAT scores from ACME High School a. Build a 82% CI for the population mean SAT score at ACME High School. Use a calculator/computer to build the CI, then round to two decimals and enter like this: (min, max). Be sure to include the parentheses or you will be marked wrong. b. Use your Cl to decide whether the mean score for ACME students differs from the national average. Yes, the mean at ACME is probably different since the Cl does not contain 1000 No, the mean at ACME is probably not different since 1000 is not close to either endpoint of the Cl Yes, the mean at ACME probably is different since 1000 is not right in the middle of the CI No, the mean at ACME is probably not different since the CI contains 1000
