A biologist assumes that there is a linear relationship between the amount of fertilizer supplied to tomato plants and the subsequent yield of tomatoes obtained. Eight tomato plants, of the same variety, were selected at random and treated weekly with a solution in which x grams of fertilizer was dissolved in a fixed quantity of water. The yield, y, is measured by kilograms and recorded. Plant
1 2 3 4 5 6 7 8
Fertilizer (x) 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5
Yield (y) 3.9 4.4 5.8 6.6 7.0 7.1 7.3 7.7

Sxy = 11.35, Sxx = 10.5, Sy = 13.755, X = 2.75, Y = 6.225
