A survey was conducted to determine the impact of contamination on property values. Home owners were randomly selected from each of seven statesA, 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. Complete parts a and b. a. Give the null and alternative hypotheses of interest to the researchers. Choose the correct answer below. 0 A- Ho5l11l12l13 il14 i'llsi'lle 7*\"7 Ha: At least two treatment means are equal 0 B.
