How To Read Z Table
Here you want the probability that z is between 1 0 and 1 0.
How to read z table. On some z tables you will find that the area corresponding to 1 09 z score is 0 3621. Then we look up a remaining number across the table on the top which is 0 09 in our example. You can see how to find the value of 0 4265 in the full z table below. In this case it is 1 0. First we find the first two digits on the left side of the z table.
First use the z table to find the value where the row for 1 0 intersects with 0 00 which is 0 1587. Find the 1 4 row and follow it across. Then follow the 0 05 column down until the row and column meet at 0 4265. In the above example we derive that eric s z score is 0 56. Once you have the z score the next step is choosing between the two tables.
Then find the value where the row for 1 0 intersects with the column for 0 00 which is 0 8413. The corresponding area is 0 8621 which translates into 86 21.
