Final answer:
The results of the experiment do not support Carl's hypothesis, as the presence or absence of ultraviolet radiation did not significantly affect the average number of deformed frogs.
Step-by-step explanation:
The results of the experiment do not support Carl's hypothesis.
While the two groups of tadpoles were placed in similar conditions, the presence or absence of ultraviolet radiation did not significantly affect the average number of deformed frogs.
This suggests that ultraviolet radiation may not be the main factor influencing frog deformities.
The results provide new information that can help Carl further investigate the causes of deformities in frogs.
