Suppose a student's score on a standardize test to be a continuous random variable whose distribution follows the normal curve. (a) if the average test score is 510 with a standard deviation of 100 points, what percentage of students scored below 300? enter as a percentage to the nearest tenth of a percent. % (b) what score puts someone in the 90th percentile? start by finding z such that p(z < z) = 0.90, then find what test score has that z value. round to the nearest whole score:
