On their respective final exams Ernest scored 88, while Emily scored 84 and Ernest is telling everyone that he scored higher than Emily. Emily thinks that the tests were scored differently by the two professors, so she asked them to provide the mean and standard deviation for their classes. With this information (see below), calculate the Z-score for Emily and the Z-score for Ernest. Ernest's Class Emily's Class Mean = 80 Standard Deviation = 6 Mean = 78 Standard Deviation = 4 Select all of the statements that are correct using the Z-scores to compare the two students. The Z-score for Emily is Z = 1.5. The Z-score for Ernest is Z = 1.33. O Relative to their individual classes, Ernest performed better. O Relative to their individual classes, Emily performed better
