Below is the data from an agricultural experiment. The purpose of the study was to see how the yield of corn changes as we change the planting rate (plants per acre).

Plants per acre Yield (bushels per acre)
12,000 150.1 113.0 118.4 142.6
16,000 166.9 120.7 135.2 149.8
20,000 165.3 130.1 139.6 149.9
24,000 134.7 138.4 156.1
28,000 119.0 150.5

Make a scatterplot of the data to help you answer the next questions. (Use a scale of yields from 100 to 200 bushels per acre. You will need to repeat each planting rate to match the number of yields shown.)
