Based on the scatterplot and the general trend of the points, it can be seen that the correlation between height and weight is negative, indicating that as height increases, weight tends to decrease. The correlation appears to be strong, with points clustered closely around a negative slope line. Therefore, the best answer choice is E, which indicates an approximate correlation of 0.95.
