Sophia Intro to Stats Unit 5 Milestone 5.What value of z* should be used to construct a 97% confidence interval of a population mean? Answer choices are rounded to the thousandths place. 1.65 1.88 1.96 2.17 RATIONALE Using the z-chart to construct a 97% CI, this means that there is 1.5% for each tail. The lower tail would be at 0.015 and the upper tail would be at (1 - 0.015) or 0.985. The value of 0.9850 is actually on the z-table exactly. 0.9850 corresponds with a z-score of 2.17.
