there is a strong positive linear correlation between the number of clear days and the height of bean plants. does this mean that more clear days cause the bean plants to grow taller?
a. no. since the number of clear days and height are linearly correlated, this means a smaller number of clear days causes the bean plants to grow taller.
b. yes. since the number of clear days and height are linearly correlated, this means a greater number of clear days causes the bean plants to grow taller.
c. yes. since the number of clear days and height are positively correlated, this means a greater number of clear days causes the bean plants to grow taller.
d. no. any number of factors could also affect the height of the bean plants.

Explanation:

Correlation does not imply causation. Just because there is a strong positive linear correlation between the number of clear days and the height of bean plants does not mean that clear days are the cause. There could be other factors (like proper watering, soil quality, etc.) that affect the height of the bean plants.

Answer:

D. No. Any number of factors could also affect the height of the bean plants.
