Question

what is true about his results?
○ they are incorrect.
○ they support his hypothesis.
○ there is not enough information to determine if his hypothesis is supported.
○ they do not support his hypothesis

tree | 1 | 2 | 3 | 4
percent sand in soil | 3% | 6% | 12% | 16%
cones produced | 50 | 55 | 61 | 70

Explanation:

As percent sand in soil increases (3%→6%→12%→16%), cones produced also increase (50→55→61→70). This positive correlation suggests the results support the hypothesis (likely about sand - cone production relationship).

Answer:

They support his hypothesis.
