Reading Improvement Program To help students improve their reading, a school district decides to implement à reading program. It is to be administered to the bottom 6% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 121.7, find the cutoff score that will make a student eligible for the program. The standard deviation is 17. Assume the variable is normally distributed. Use a graphing calculator and round the answer to the nearest whole number.
