In a normal distribution, the mean corresponds to: Standard Score: z = Percentile: Which of the following statements are TRUE about the normal distribution? Check all that apply. 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. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. A z-score is the number of standard deviations a...

From our last lesson about z-score, we know that z-score corresponds to different proportions in a normal distribution. It might be handy to remember that: 1) 68.26% of all observed data values will fall within ONE standard deviation from the mean (that is to the left and to the right). 2) 95.44% of all observed data values will fall within TWO standard deviations from the the mean (again, that is to the left and to the right). 3) 99.74% of...

Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P 8 3.Find the z-score...
