Step 2 Since we are dealing with an area to the left of z, we can use the Standard Normal Distribution Table directly. \begin{tabular}{|c|c|c|c|c|c|c|} \hline z & 0.04 & 0.05 & 0.06 & 0.07 & 0.08 & 0.09 \\ \hline -1.1 & 0.1271 & 0.1251 & 0.1230 & 0.1210 & 0.1190 & 0.1170 \\ \hline \end{tabular} We scan the table in search of the exact value 0.12. However, this area is not in our table, so we will need to use approximation techniques. The area 0.1190 is slightly smaller than 0.12 and is associated with the z value _. The area 0.1210 is slightly larger than 0.12 is associated with the z value _. The average of these two z values is z = 0.12, which is halfway between 0.1190 and 0.1210, is the approximated z value associated with the area 0.12.

          Step 2
Since we are dealing with an area to the left of z, we can use the Standard Normal Distribution Table directly.
\begin{tabular}{|c|c|c|c|c|c|c|}
\hline
z & 0.04 & 0.05 & 0.06 & 0.07 & 0.08 & 0.09 \\
\hline
-1.1 & 0.1271 & 0.1251 & 0.1230 & 0.1210 & 0.1190 & 0.1170 \\
\hline
\end{tabular}
We scan the table in search of the exact value 0.12. However, this area is not in our table, so we will need to use approximation techniques.
The area 0.1190 is slightly smaller than 0.12 and is associated with the z value _____. The area 0.1210 is slightly larger than 0.12 is associated with the z value _____. The average of these two z values is z = 0.12, which is halfway between 0.1190 and 0.1210, is the approximated z value associated with the area 0.12.

Step 2
Since we are dealing with an area to the left of z, we can use the Standard Normal Distribution Table directly.

z 0.04 0.05 0.06 0.07 0.08 0.09

-1.1 0.1271 0.1251 0.1230 0.1210 0.1190 0.1170

We scan the table in search of the exact value 0.12. However, this area is not in our table, so we will need to use approximation techniques.
The area 0.1190 is slightly smaller than 0.12 and is associated with the z value . The area 0.1210 is slightly larger than 0.12 is associated with the z value . The average of these two z values is z = 0.12, which is halfway between 0.1190 and 0.1210, is the approximated z value associated with the area 0.12.
