According to National Collegiate Athletic Association (NCAA) data, the means and standard deviations of eligibility and retention rates (based on a 1,000-point scale) for the 2013-2014 academic year are presented, along with the fictional scores for two basketball teams, A and B. Assume that rates are normally distributed.

	Mean	Standard Deviation	Team A	Team B
Eligibility	983	33	971	987
Retention	976	34.9	958	970
