You have a sample of test scores, the sample mean of the test scores is 70.5, and the standard deviation of the test scores is 10, compute a z-score for an individual score of 85, then using that z-score, what is the percentage of scores from this sample that is less than 85? (your answer should contain four decimal places, example = .1234)
