Amateur radio operators (hams) communicate with one another all over the world, and many help coordinate relief efforts during a natural disaster. Unlike the 5-watt power limit on a CB radio, ham radios can have as much as 1500 watts of power. A random sample of amateur radio operators was obtained from four states. The power on each transmitter was measured (in watts), and the summary statistics are given in the following table.

Assume the underlying transmitter power distributions are continuous. Use the Kruskal-Wallis test with a = 0.025 to determine whether there is any evidence to suggest that at least two transmitter power populations are different. Find the p value associated with this test.
