2. At Western University the historical mean of scholarship examination scores for freshman applications is 900. A historical population standard deviation of g = 100 is assumed known. Each year, the assistant dean uses a sample of applications to determine whether the mean examination score for the new freshman applications has changed. A sample of 100 applications provided a sample mean of 890. Perform the appropriate hypothesis test using a = 0.05.
