City planners believe that lorger cities ore populated by older residents. To investigate the relationship, data on population and medianage in 10 lorge cities were collected.Populationcity (inmillions)2.833Median ageCityChicago, ILDallas, TX31.51.2332.1443e.5Houston, TX30.9Los Angeles, CANew York, NYPhiladelphia, PAPhoenix, AZSan Antonio, TXSan biego, CASan Jose, CA3.84931.634.234.23e.78.2141.4481.51331.732.532.61.2971.257e.93eE Click here for the Excel Data Filea.
