Conclusion in nontechnical terms?

Question

Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. An entomologist writes an article in a scientific journal which claims that fewer than 14 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms. Answer choices are below: A) There is not sufficient evidence to support the claim that the true proportion is greater than 14 in ten thousand. B) There is not sufficient evidence to support the claim that the true proportion is less than 14 in ten thousand. C) There is sufficient evidence to support the claim that the true proportion is greater than 14 in ten thousand. D) There is sufficient evidence to support the claim that the true proportion is less than 14 in ten thousand.

Answer 1

From the ref., "A null hypothesis is a statistical hypothesis that is tested for possible rejection under the assumption that it is true (usually that observations are the result of chance)."
Based on this definition, I'd say that the hypothesis test's "rejection of the null hypothesis" means that there is statistical significance in the entomologist's observations, answer (D).
