For a normal distribution, find the z-score that separates the distribution as follows: Separate the highest 30% from the rest of the distribution. Separate the lowest 40% from the rest of the distribution. Separate the highest 75% from the rest of the distribution. For the numbers below, find the area between the mean and the z-score: z = 1.17

Using z-scores and percentiles lead to the equivalent results and the same conclusion.. Using the specified normal distribution X~N(3.0, 0.7) and Y~N(80, 10) give the same probabilities and percentiles as are obtained by using the Z score with the standard normal distribution, Z ~ N(0, 1) CHAPTER 6: THE NORMAL PROBABILITY DISTRIBUTION: PRACTICE

A normal distribution of scores has a standard deviation of 10. Find the z-scores corresponding to each of the following values: A score that is 20 points above the mean. z=2. A score that is 10 points below the mean. z=-1. A score that is 15 points above the mean z=1.5. A score that is 30 points below the mean. z…
