You are given a 2003 summary report of SAT scores for 1,000 grade 9 students from a large county in Florida. The scores are assumed to be normally distributed, and have a mean of 500 and a standard deviation of 80.

1. For this distribution determine which scores are associated with each of the following z-scores: -2,-1,0,1,2.

2. For this distribution determine the percentage of examinees that fall below each of the z-scores in question 1 (e.e. what is the percentile rank associated with each of the z-scores).

Please give me some direction in how to compute this.

Thank you,
