The reading speed of sixth-graders is normally distributed with a mean speed of 125 words per minute and a standard deviation of 24 wpm. A school psychologist wants to determine reading rates for unusual students (slow and fast). Determine the reading rates of the middle 90% of all sixth-graders. What are the cutoff points for unusual readers? [a] and [b] Round to two decimal places
