##### MS 150 Statistics prequiz spring 2006 • Name:

The colors (hues) of the rainbow were analyzed using a system of color angles where red has hue angle of 0°, green has a hue angle of 120°, and blue has a hue angle of 240°. The measurement of hues found in an actual rainbow are shown in the right-hand column in the table seen on the right side of this page. Use this hue angle data to perform the following calculations.
