Question 1198428: 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 14% 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 124.8 , find the cutoff score that will make a student eligible for the program. The standard deviation is 18 . Assume the variable is normally distributed. Round z-value calculations to 2 decimal places and the final answer to the nearest whole number.

Invnorm(.14) = -1.08
z+=blue+%28x+-+mu%29%2Fblue%28sigma%29
OR blue%28sigma%29%2Az+%2B+mu=blue+%28x%29
blue%2818%29%2A%28-1.08%29+%2B+124.8+=blue+%28x%29 = 105.36
Cut-off Score is 105
