Which of the following statements are TRUE about the normal distribution? Check all that apply. A z-score is the number of standard deviations a specific data value is from the mean of the distribution. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. The area to the left of a z-score plus the area to the right of that same z-score will always equal 1. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean. The mean corresponds to the z-score of 1.Below is the graph of a normal distribution with mean u = 54 and standard deviation o = 3.3 A B C Identify each of the following values: A = B = C =
