1. The problem statement, all variables and given/known data In math 334 one semester, the average student made 1200 computations per month with a standard deviation of 150 computations. Assume that the number of computations is approximated by a normal curve. Find the percent of students making between 1200 and 1600 computations a month. 2. Relevant equations standard bell curve equation. I don't really know what specific ones I'm supposed to use for a problem like this. 3. The attempt at a solution I figured that the answer would have to be the prob. of a student making less than 1200* the prob of a student making less than 1600. Which would be 1/2*prob of making less than 1600, which I can't seem to figure out.
