Formulate the indicated conclusion in nontechnical terms Be

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 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.

A. There is not sufficient evidence to support the claim that the true proportion is less than 3 in ten thousand.

B There is not sufficient evidence to support the claim that the true proportion is greater than 3 in ten thousand.

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

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

Solution

Null hypothesis here would be that \"proportion is not less than 3 in 10K\", rejection of null means:

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