A survey was conducted to determine the impact of contamination on property values. Home owners were randomly selected from ea 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. b. An ANOVA summary table is shown to the right. Use the information provided to conduct the hypothesis test, States part a. Use a-0.05.

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
