Derek runs an apple orchard, and his trees did not produce many apples this season. His friends tell him that adding more fertiliser to the soil may help for next season. Since fertiliser is expensive, Derek decides to test this theory on some small plots of land with equal area. He varies the kilograms of fertiliser used in each plot, x, and counts the number of apples produced on each, y, at the end of one season. The least squares regression line of this data set is: y = 15.082x + 171.458 Complete the following sentence: If one additional kilogram of fertiliser was used in a plot, the least squares regression line predicts an additional apples would be produced on it that season.
