14-16. Two brands of fertilizer (call them A and B) are being tested on two identical plots of land planted with wheat. Each plot is divided into 10 equal sections. Yields per section have been determined for each brand of fertilizer. For α = 0.05, use the K-S test to determine if the two samples were drawn from the same population distribution.
