You have been asked to conduct a national study of urban home selling prices to determine if there has been an increase in selling prices over time. There has been some concern that housing prices in major urban areas have not kept up with inflation over time. Your study will use data collected from Atlanta, Chicago, Dallas, and Oakland, which is contained in the data file House Selling Price. Formulate an appropriate hypothesis test and use your statistical computer package to compute the appropriate statistics for analysis. Perform the hypothesis test and indicate your conclusion.

Repeat the analysis using data from only the city of Atlanta.
