Home owners were randomly selected from each of seven states-A, B, C, D, E, F, and G. Each homeowner was asked to estimate the property value of a home located in an area contaminated by a certain substance. The dependent variable of interest was the substance discount percentage (the difference between the current home value and the estimated value after contamination, as a percentage). The researchers were interested in comparing the mean substance discount percentages across the seven states.
