lee looked at the results of an exam he had just given to his grade 2 math class. he saw that louise had a score of 95%. he also saw that the standard deviation for the test was 0. if arif was also in his grade 2 math class, what mark did arif get on the exam?

PsyDAG,
If SD = 0, there is no variability. Everyone got 95%.
