Use the zscores from the previous page to fill in the first column; use the ztable to fill in the second column; use (1- ztable reading ) to fill in the third column. Then answer the questions. zscore Read ztable 1- ztable reading A 0.9192 68708 0.1292 0.9599 0.0401 D. 0.8849 0.1151 0.3340 0.1460 F 6.2266 0,7734 Using both the table and the data from previous page, answer the questions: 1. For A, what percent of data will be greater than 87? 2. For C, what percent of data will be less than 14? 3. For F, what percent of data will be left of 6.2? 4. For B, what percent of data will be right of 117? 5. For D, what percent of data will be at least 61?
