For the purposes of this exercise, consider the mean and the median to be "approximately equal" if their difference is less than 1. Choose the correct answer below. O A. Because the mean is greater than the median, this distribution's shape is right-skewed. O B. Because the mean is less than the median, this distribution's shape is left-skewed. O C. Because the mean is less than the median, this distribution's shape is right-skewed. O D. Because the mean and median are approximately equal, this distribution's shape is symmetrical
