Graduation Success Rate

The National Collegiate Athletic Association (NCAA) measures the Graduation Success Rate (GSR), which is the percentage of eligible athletes who graduate within six years of entering college.  According to the NCAA, the GSR for all scholarship athletes in a particular division is 61%. The GSR for all students in this division is 56%.  Suppose the NCAA report was based on a sample of 500 student athletes, of which 305 graduated within six years.  Is this sufficient information to conclude that the GSR for all scholarship athletes in this division differs from 56%?  Test using a = 0.05.What is the rejection region?
