A horticulturalist claims that a seaweed extract in compost will in- crease the leaf size of a plant. The area of the leaves of 10 plants were measured before and after the seaweed extract was added, de- noted X, and Y, respectively. The values are in cm?. Let D, be the difference D, = X, – Y;. The following information is available: %3D EDi = 31.71 and D? = 120.358. %3D (b) Simply showing that the leaf size has increased is not sufficient; redo the test for an increase of 5 cm2.
