F=
Identify the p-value
P=
A survey was conducted to determine the impact of contamination on property values. 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. Complete parts a and b. a. Give the null and alternative hypotheses of interest to the researchers. Choose the correct answer below 0 A. Ho: At least two treatment means differ Ha At least two treatment means are equal Ho: At least two treatment means are equal C. H At least two treatment means differ b.
