    type of rather expensive fertilizer which would
    supposedly significantly increase his production.
    The frugal farmer wanted to test the new

    required to fertilize a farm of his size. He
    therefore selected 15 parcels of land on his
    property and divided them each into two portions.
    He bought just enough of the new fertilizer to
    spread over one half of each parcel and then
    spread the old fertilizer over the other half of
    each parcel. His yields in pounds per tomato
    plant were as follows
