A certain psychological test measures empathy and emotional intelligence. The mean and standard deviation of the difference, D, in scores for a randomly selected pair of senior and first-year students are up = 19 and op = 44.6878. How can these values be interpreted? Check all that apply. * Seniors are 19 points more empathetic than first-year students. ✓ The average of the difference of scores would be about 19 points if you were to take many, many samples of first-year and senior pairs. * For a pair of randomly selected first-year and senior students, the difference of their scores is usually 19 points. ✓ For a pair of randomly selected first-year and senior students, the difference of their scores typically varies from the mean of 19 points by about 45 points. * Students who take this psychological test should expect their score to vary from the mean by about 45 points, regardless of their class standing. €
