There is no mode in this data set. Part 4 d) Describe the shape of the distribution. 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. A. Because the mean is greater than the median comma this distribution's shape is right dash skewed. B. Because the mean is less than the median comma this distribution's shape is right dash skewed. C. Because the mean is less than the median comma this distribution's shape is left dash skewed. D. Because the mean and median are approximately equal comma this distribution's shape is symmetrical. x overbar(Type an integer or decimal rounded to three decimal places as needed.)Median(Do not round.))Select the correct choice below and, if necessary, f
