In a recent year 76,531 tenth-grade Indiana students took the English/language arts exam. The mean score was 572 and the standard deviation was 51. (a)Assuming that these scores are approximately Normally distributed, N(572,51), use the 68-95-99.7 Rule to give an interval for the range of scores that includes 95% of these students. (b)A certain student received a score of 600. Find the z-score for this student. (c)What percent of these students have a score above 600?
