Use the table below to find the percentage of data items in a normal distribution that lie between $z=-0.9$ and $z=0.9$. Click the icon to view the table. The percentage of data items in a normal distribution that lie between $z=-0.9$ and $z=0.9$ is $\%$.

Step 1 ：Find the area to the left of z=0.9 using the standard normal distribution table: 0.8159

Step 2 ：Find the area to the left of z=-0.9 using the standard normal distribution table: 0.1841

Step 3 ：Subtract the area to the left of z=-0.9 from the area to the left of z=0.9: 0.8159 - 0.1841 = 0.6318

Step 4 ：Convert the result to a percentage: 0.6318 * 100 = 63.18%

Step 5 ：The percentage of data items in a normal distribution that lie between z=-0.9 and z=0.9 is \(\boxed{63.18\%}\)
