     Florida   condominiums are popular winter retreats for many North Americans. In recent   years the price has steadily increased. A real estate agent wanted to know   why prices of similar size apartments in the same building vary. A possible   answer lies in the floor. It may be that the higher the floor, the greater   the sale price of the apartment. He recorded the price (in $1000's) of 1200   sq. ft. condominiums in several buildings in the same location that have sold   recently and the floor number of the condominium. 

     Floor   (x)  Price (y)   22 212   20 225   16 261   4 184   18 232   18 222   21 210   13 201   14 189   8 200   4 203   2 196   16 220   13 245   12 211   8 216   21 256   7 173   8 194   8 196   23 182   21 230   10 216   9 188   15 210   1 216   27 218   8 169   27 235   8 227   10 191   1 203   27 223   14 206   28 204   4 190   28 246   8 168   10 193   12 186   7 193   27 224   21 231   6 183   21 224   9 212   12 232   7 193   18 233   12 249
