Question 6

An atmospheric scientist records the relationship between the altitude hhh (in km) and the air temperature TTT (in ∘C{}^\circ\text{C}∘C) above a fixed ground location. The resulting scatter graph shows that as altitude increases, the temperature decreases consistently. The data points are positioned extremely close to a straight line of best fit, with almost no visible deviation from the linear path.

Which of the options below best describes the correlation between hhh and TTT?

[ ] moderate positive

[ ] strong positive

[ ] moderate negative

[ ] strong negative

Scatter graph of air temperature against altitude, showing a strong negative correlation with points very close to a descending straight-line pattern.
