What is the z-score?



Enter your answer,as a decimal to the nearest hundredth, in the box.

Answer 1

Answer: 0.32

Step-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.

Answer 2

Z-score is 0.32

From the given z-table, observe  that the value 0.1271 is not in the table but is between 0.1255 and 0.1293 which are located on the z-table at 0.32 and 0.33.

This means, the given value is closer to 0.1255

Hence the z-score is 0.32
