An entomologist writes an article in a scientific journal which claims that fewer than 3 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.

C. There is sufficient evidence to support the claim that the true proportion is less than 3 in ten thousand.

Step-by-step explanation:

The claim of the researcher is that fewer than 3 in ten thousand male fireflies are unable to produce light due to a genetic mutation.

Then, the conclusion of the hypothesis test is to reject the null hypothesis. The null hypothesis stated the opposite of the researchers claim: that 3 or more in ten thousand male fireflies are unable to produce light due to a genetic mutation.

This means that the the researcher now has statistical evidence to support his claim.
