30 points!!A scientist measured the amounts of fertilizer given to plants, the heights to which the plants grew, and the amount of fruit the plants produced.The scientist graphed the two sets of data and found that a positive correlation exists in each set. Which statement explains whether there is a relationship between the height of the tree and the amount of fruit produced.A..Although fertilizer is in both data sets and is positively correlated, only a weak correlation can exist between tree height and fruit yield.B..Although fertilizer is in both data sets and is positively correlated, it is impossible for any correlation to exist between tree height and fruit yield.C.Since fertilizer is in both data sets and is positively correlated to both tree height and fruit yield, it is likely that tree height and fruit yield are negatively correlated.D..Since fertilizer is in both data sets and is positively correlated to both tree height and fruit yield, it is like that tree height and fruit yield are also positively correlated.
