C12. According to the same National Collegiate Athletic AssoC 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 a. On which criterion (eligibility or retention) did Team A do better than Team B? Calculate appropriate statistics to answer this question.

Question
**C12. National Collegiate Athletic Association Data Analysis**

The data here are based on the National Collegiate Athletic Association for the 2013–2014 academic year. The information includes means and standard deviations of eligibility and retention rates, given on a 1,000-point scale, for two fictional basketball teams, A and B. It's assumed that these rates follow a normal distribution.

**Data Table:**

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

**Questions:**

a. **Comparison of Team Performance:** Determine on which criterion (eligibility or retention) Team A performed better than Team B using appropriate statistical measures.

b. **Proportion Below Team B's Retention Rate:** Calculate what proportion of teams have retention rates below Team B's rate.

c. **Percentile Rank of Team A's Eligibility Rate:** Determine the percentile rank of Team A's eligibility rate.
