This sketch shows the normal curve 4 standard deviations above and below the mean: . You can change the Mean and Standard Deviation, which will relabel the x-axis. In reality, the curve would also be dilated and translated, but this sketch fixes the relative shape. Find a percentage for an interval [Lower, Upper]
- Check the box.
- Input the Lower Bound
- Input the Upper Bound
- The area under the curve will be highlighted and the percentage of values in this interval will be shown.
- Left Tail: such that of the values are to the left of it.
- Center: such that of the values are in this interval centered at .
- Right Tail: such that of the values are to the right of it.
