Each year, the assistant dean uses a sample of applications to determine whether the mean examination score for the new freshman applications has changed.

b. What is the 95% confidence interval estimate of the population mean examination score if a sample of 200 applications provided a sample mean = 935?
c. Use the confidence interval to conduct a hypothesis test. Using a = .05, can the assistant dean conclude that the mean examination score for the new freshman applications has changed?
