In a reading class students can read an average of 181 words per minute with a standard deviation of 18 words per minute. The bottom 25% of the class will be placed in a special helping class to assist them with reading strategies. What is the cut-off number of words per minute a student must be able to read in order to not be placed in the reading helping class?
