The Construction Labor Research Council lists a number of construction labor jobs that seem to pay approximately the same wages per hour. Some of these are bricklaying, iron working, and crane operation. Suppose a labor researcher takes a random sample of workers from each of these types of construction jobs and from across the country and asks what their hourly wages are. If this survey yields the following data, is there a significant difference in mean hourly wages for these three jobs? If there is a significant difference, use the Tukey-Kramer procedure to determine which pairs, if any, are also significantly different. Let α =.05.
