The FICO credit score is used by banks and other lenders to determine whether someone is a good credit risk. Scores
range from 300 to 859 with a score of 720 or more indicating a very good credit score. An economist wants to
determine whether the mean FICO score is lower than the cutoff of 720. She finds that a random sample of 100 people
had a mean FICO score of 703. If the population standard deviation is 92, can the economist conclude that the mean
FICO score is less than 720? Let a = 0.05
