22. Reading Improvement Program To help students
improve their reading, a school district decides to
implement a reading program. It is to be administered to
the bottom 5% 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 122.6,
find the cutoff score that will make a student eligible for
the program. The standard deviation is 18. Assume the
variable is normally distributed.
