Find the indicated area under the curve of the standard normal distribution; then convert it to a percentage and fill in the blank. About % of the area is between z=-2 and z=2 (or within 2 standard deviations of the mean). About % of the area is between z=-2 andz=2 (or within 2 standard deviations of the mean). (Round to two decimal places as needed.)

### Educational Exercise on Standard Normal Distribution

**Task:**
Find the indicated area under the curve of the standard normal distribution, convert it to a percentage, and fill in the blank.

- About ______% of the area is between \( z = -2 \) and \( z = 2 \) (or within 2 standard deviations of the mean).
- About \(\_\_\_\_\)% of the area is between \( z = -2 \) and \( z = 2 \) (or within 2 standard deviations of the mean).

**Instructions:**
- Round to two decimal places as needed.
- Enter your answer in the answer box. 

This exercise involves calculating the percentage of data that falls within two standard deviations from the mean in a standard normal distribution, a common application of statistics in various fields.
