A:
Answer: 0.32Step-by-step explanation:Look at the z-table (below) to find 0.1271. Notice that the value is not on the table but is between 0.1255 and 0.1293 which are located on the z-table at 0.32 and 0.33. We could estimate the z-score to be 0.325, however the instructions state to provide the value to the nearest hundredth. The given value is closer to 0.1255 so use 0.32 as the z-score.NOTE: It is possible that the question was supposed to be 0.1217 (the last two digits reversed). If that is the case, then the z-score is on the table at 0.31.
