Question: In hilly areas farmers often contour their aids to reduce the erosion doe to water flow. This might have the unintended effect of changing the yield since the rows may not be aligned in an east west direction to take advantage for direct sunlight.

The following summary statistics show the yields in hundreds of bushels per acre of randomly selected plots of land along hillsides as well as level plots of land nearby with similar soil characteristics.

Quantiles

Level Minimum 10.0% 25.0% Median 75.0% 90.0% Maximum

Level 10.9 10.9 13.3 29.2 58.1 97.4 100.0

Level 10.9 11.2 18.5 39.3 61.5 103.4 118.0

Means and Std Deviations

(A) Draw side by side box plots that show the yields of the two types of land.

(B) Describe the shape and any unusual features of both box plots.

(C) Based on your plots, what can you conclude about the types of land.
