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

The hypothesis is the claim--"Fewer that 14 in 10,000 fireflies can't produce light." The null hypothesis is the exact opposite--it's the claim that the hypothesis is false. The null hypothesis is "More than 14 in 10,000 fireflies can't produce light."

After the experiment, the null hypothesis was rejected. That means there was sufficient evidence to say that the null hypothesis is not true. Since the null hypothesis states that the hypothesis is false, rejecting the null hypothesis is the same as accepting the hypothesis. So the answer is D. There is sufficient evidence to support the claim that the true population is less than 14 in 10,000.

Answer 2

There is sufficient evidence to support the claim that the true proportion is less than in ten thousand.
