Basis for the Range Rule of Thumb and the Empirical Rule. In Exercise, find the indicated area under the curve of the standard normal distribution, then convert it to a percentage andfill in the blank. The results form the basis for the range rule of thumb and the empirical rule introduced in Section 3-3.

About_____% of the area is between z = − 2 and z=2 (or within 2 standard deviation of the mean).

Step 1

Step 2

Use Table: Standard normal (*z*) distribution to find the areas.

**Procedure:**

For *z* at –2.00,

- Locate –2.0 in the left column of the table.
- Obtain the value in the corresponding row below 0.00

Step 3

For *z* at 2.00,

- Locate 2.0 in the left column of the table.
- Obtain the va...
