Assessed Land Values A reporter hypothesizes that the average assessed values of land in a large cityhave changed during a 5-year period. A random sample of wards is selected, and the data (inmillions of dollars) are shown. At a = 0.05, can it be concluded that the average taxable assessedvalues have changed?
