Is there a difference in the length of suspension bridges in the northeast, southeast, and far west parts of the United States? The following table shows the lengths (in feet) of seven bridges in the northeast, nine bridges in the southeast, and eight bridges in the far west. Conduct an appropriate test of hypothesis on the following data. Do not assume the bridge lengths follow a normal probability distribution. Use the .05 significance level.
