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.
Eligibility Mean =983, Eligibiity Standard Dev =33
Team A Eligibility =971, and Team B Eligibility =987
Retention mean =976, RetentionStandard Dev = 34.9
Team A Retention = 958 and Team B Retention = 970
