Section 5.3 Problems 11-12. Use the Standard Normal Distribution Table to nd the z-score that corresponds to the given cumulative area. If the area is not in the table use the entry closest to the area, unless the area is exactly halfway between two entries. In that case, use the z-score halfway between the corresponding z-scores. 11. Area = 0.2981 12. Area = 0.9844 13. A normal distribution has u = 185 and a = 7.4. Find the :c-value that has 28.4% of the standard normal distribution's area to its left. Section 5.4 Problems 14-15. A population with n = 275 has a mean u = 624 and a standard deviation 0' = 36. 14. Find #5. 15. Find 05. 16.True or false? As the size of a sample decreases, the standard deviation of the distribution of sample means decreases. Problems 17-18. Asample with n = 750 is taken from a population that has a mean, u = 125 and the standard deviation, 0 = 25. 17. What is P(5
