For questions 1-5, find the area under the normal distribution curve given the z-score or interval. Show any calculations that you use. Your work and explanations must reflect the use of the z-table provided in this lesson. 1. z = 3.05 2. z = -.42 3. -2.61 < z < 2.61 4. z > 1.93 5. .52 < z < 1.21 For Questions, 6 - 10 find the z-scores that satisfies the condition. Show any calculations that you use. 6. The z-score that separates the lower 50% of the distribution from the upper 50% of the distribution. 7. The z-score for the cumulative 20% of the data distribution. 8. The z-score for the upper 20% of the data distribution. 9. The z-score that corresponds to a cumulative value of .3974 10. The z-score that represents the cumulative value of .2984
