There are three grades in a report card that you want to interpret in terms of performance: Mathematics (75), English (85), and Science (90). The means are 78, 83, and 88, respectively. The standard deviations are 3, 5, and 4, respectively, is the information sufficient for you to compare grades? If so, discuss your process through computations and interpretation of your answer. (There are three grades, therefore, there are three computations and interpretations.)
