g Refer to the Environmental Science and Technology (January 2005)study of the reliability of a commercial kit totest for arsenic in groundwater, Exercise 4.12(p. 187). Using the data in the ASWELLS file, you fit a first-order model for arsenic level (y)as a function of latitude, longitude, and depth. Based on the model statistics, the researcher concluded that the arsenic level is highest ata low latitude, high longitude, and low depth. Do you agree? If so, find a 95% predictioninterval for arsenic level for the lowest latitude, highest longitude, and lowest depth that arewithin the range of the sample data. Interpret theresult.
