The scores on a university examination are Normally distributed with a mean of 62 and a standard deviation of 11. If the bottom 5% of students will fail the course, what is the lowest mark that a student can have and still be awarded a passing grade?
This question asks you find the score so that 5% of the scores are below that value.
General Idea: Convert a z-score after finding it, given a certain percentage.
Help please.
