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 \( \square \% \) of the area is between \( z=-2 \) and \( z=2 \) (or within 2 standard deviations of the mean). (Round to two decimal places as needed.)

Use \( <,> \), or \( = \) to \[ \begin{array}{rrr}-3 & \text { Ø̈ } & -10 \\ -7 & \square & -8 \\ -6 & \square & 4\end{array} \]

Evaluate the following. \[ \begin{array}{r}-3 \times(-7)=\square \\ -20 \div 5=\square\end{array} \]
